I'm uploading a file to a SharePoint Document library using the following code:
string fileToUpload = oFile.PostedFile.FileName;
using (SPSite oSite = new SPSite(spsite))
{
using (SPWeb oWeb = oSite.OpenWeb())
{
SPList library = oWeb.Lists[documentLibraryName];
using (FileStream fs = new FileStream(fileToUpload, FileMode.Open))
{
//more logic here
This works fine in my dev environment, but when I move it to QA, I get the following error when try to upload a file:
System.IO.FileNotFoundException:
Could not find file 'c:\windows\system32\inetsrv\file_to_upload'.
I have googled around, and it seems like I may need to use PostedFile.InputStream instead of PostedFile.Name.
But if set fileToUpload equal to oFile.PostedFile.InputStream, then I am not able to use this bit of code anymore:
using (FileStream fs = new FileStream(fileToUpload, FileMode.Open))
I would like to still use this code as I need to access fs.name later on in my code.
Any idea how I could get this problem resolved?
Give it a try, this might be helpful

I have few files in azure blobs that are stored with unique file names and when the client wants to download, i want to rename to a friendly name.
I'm still using 2014 azure storage dlls in my project and i'm not planning to update them anytime soon. So i can't use built-in ContentDeposition and rename it.
I tried using following code in my controller:
var blob = blobStorage.GetBlobRef("https://mysite.blob.core.windows.net/my-container/WERF3234435FFF_ERFas23E.doc");
MemoryStream memStream = new MemoryStream();
blob.DownloadToStream(memStream);
Response.ContentType = blob.Properties.ContentType;
Response.AddHeader("Content-Disposition", "Attachment; filename=abcd_New.doc");
Response.AddHeader("Content-Length", blob.Properties.Length.ToString());
Response.BinaryWrite(memStream.ToArray());
but its not downloading the file.
I also tried using this:
MemoryStream memStream = new MemoryStream();
blob.DownloadToStream(memStream);
System.Web.HttpContext.Current.Response.Clear();
System.Web.HttpContext.Current.Response.ContentType = blob.Properties.ContentType;
System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", "Attachment; filename=" + friendlyName.doc);
System.Web.HttpContext.Current.Response.AddHeader("Content-Length", blob.Properties.Length.ToString());
System.Web.HttpContext.Current.Response.BinaryWrite(memStream.ToArray());
System.Web.HttpContext.Current.Response.End();
I have my business logic in a separate solution and getting the blob reference from there to my main solution.
Am i missing something?
When we're talking about ASP.NET MVC, I'm missing the Controller/Action in your code? You're not supposed to write to the HttpContext yourself when doing ASP.NET MVC. You have ActionResults for that.
public ActionResult Download()
{
// ...
var bytes = memStream.ToArray();
return File(bytes, System.Net.Mime.MediaTypeNames.Application.Octet, "abcd_New.doc");
}
The browser will decide whether to open the file download or open it directly within the browser window. If you want to control that, you will need the following piece of code before you call the return File(... method:
var contentDisposition = new System.Net.Mime.ContentDisposition
{
FileName = "abcd_New.doc",
Inline = false // true will try to open in Browser, false will download
};
Response.AppendHeader("Content-Disposition", contentDisposition.ToString());
We need to flush our response after wrote a file to response. I use the code which you provided. After adding following code, I can see the file can be download from server.
Response.BinaryWrite(memStream.ToArray());
Response.Flush();
Response.End();
I got an assignment to see if I can make power app that will generate some PDF file for end user to see.
After through research on this topic I found out that this is not an easy to achieve :)
In order to make power app generate and download/show generated pdf I made these steps:
Created power app with just one button :) to call Azure function from step 2
Created Azure function that will generate and return pdf as StreamContent
Due to power app limitations (or I just could not find the way) there was no way for me to get pdf from response inside power app.
After this, I changed my Azure function to create new blob entry but know I have problem to get URL for that new entry inside Azure function in order to return this to power app and then use inside power app Download function
My Azure function code is below
using System;
using System.Net;
using System.Net.Http.Headers;
using System.Runtime.InteropServices;
using Aspose.Words;
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log, Stream outputBlob)
{
log.Info($"C# HTTP trigger function processed a request. RequestUri={req.RequestUri}");
var dataDir = #"D:/home";
var docFile = $"{dataDir}/word-templates/WordAutomationTest.docx";
var uid = Guid.NewGuid().ToString().Replace("-", "");
var pdfFile = $"{dataDir}/pdf-export/WordAutomationTest_{uid}.pdf";
var doc = new Document(docFile);
doc.Save(pdfFile);
var result = new HttpResponseMessage(HttpStatusCode.OK);
var stream = new FileStream(pdfFile, FileMode.Open);
stream.CopyTo(outputBlob);
// result.Content = new StreamContent(stream);
// result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
// result.Content.Headers.ContentDisposition.FileName = Path.GetFileName(pdfFile);
// result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
// result.Content.Headers.ContentLength = stream.Length;
return result;
}
I left old code (the one that streams pdf back under comments just as reference of what I tried)
Is there any way to get download URL for newly generated blob entry inside Azure function?
Is there any better way to make power app generate and download/show generated PDF?
P.S. I tried to use PDFViewer control inside power app, but this control is completely useless cause U can not set Document value via function
EDIT: Response from #mathewc helped me a lot to finally wrap this up. All details are below.
New Azure function that works as expected
#r "Microsoft.WindowsAzure.Storage"
using System;
using System.Net;
using System.Net.Http.Headers;
using System.Runtime.InteropServices;
using Aspose.Words;
using Microsoft.WindowsAzure.Storage.Blob;
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log, CloudBlockBlob outputBlob)
{
log.Info($"C# HTTP trigger function processed a request. RequestUri={req.RequestUri}");
var dataDir = #"D:/home";
var docFile = $"{dataDir}/word-templates/WordAutomationTest.docx";
var uid = Guid.NewGuid().ToString().Replace("-", "");
var pdfFile = $"{dataDir}/pdf-export/WordAutomationTest_{uid}.pdf";
var doc = new Document(docFile);
doc.Save(pdfFile);
var result = new HttpResponseMessage(HttpStatusCode.OK);
var stream = new FileStream(pdfFile, FileMode.Open);
outputBlob.UploadFromStream(stream);
return req.CreateResponse(HttpStatusCode.OK, outputBlob.Uri);
}
REMARKS:
Wee need to add "WindowsAzure.Storage" : "7.2.1" inside project.json. This package MUST be the same version as one with same name that is in %USERPROFILE%\AppData\Local\Azure.Functions.Cli
If you change your blob output binding type from Stream to CloudBlockBlob you will have access to CloudBlockBlob.Uri which is the blob path you require (documentation here). You can then return that Uri back to your Power App. You can use CloudBlockBlob.UploadFromStreamAsync to upload your PDF Stream to the blob.
Hi I'm trying to upload a file to sharepoint 2010 using the client api with meta data and also checkin the file after I'm done. Below is my code:
public void UploadDocument(SharePointFolder folder, String filename, Boolean overwrite)
{
var fileInfo = new FileInfo(filename);
var targetLocation = String.Format("{0}{1}{2}", folder.ServerRelativeUrl,
Path.AltDirectorySeparatorChar, fileInfo.Name);
using (var fs = new FileStream(filename, FileMode.Open))
{
SPFile.SaveBinaryDirect(mClientContext, targetLocation, fs, overwrite);
}
// doesn't work
SPFile newFile = mRootWeb.GetFileByServerRelativeUrl(targetLocation);
mClientContext.Load(newFile);
mClientContext.ExecuteQuery();
//check out to make sure not to create multiple versions
newFile.CheckOut();
// use OverwriteCheckIn type to make sure not to create multiple versions
newFile.CheckIn("test", CheckinType.OverwriteCheckIn);
mClientContext.Load(newFile);
mClientContext.ExecuteQuery();
//SPFile uploadFile = mRootWeb.GetFileByServerRelativeUrl(targetLocation);
//uploadFile.CheckOut();
//uploadFile.CheckIn("SOME VERSION COMMENT I'D LIKE TO ADD", CheckinType.OverwriteCheckIn);
//mClientContext.ExecuteQuery();
}
I'm able to upload the file but I can't add any meta data and file is checked out. I want to add some meta data and checkin the file after I'm done.
My SharePointFolder class has the serverRelativeUrl of the folder path to upload to. Any help greatly appreciated.
You need a credential before the executeQuery(); and SaveBinaryDirect();
For example:
mClientContext.Credentials = new NetworkCredential("LoginID","LoginPW", "LoginDomain");
SPFile newFile = mRootWeb.GetFileByServerRelativeUrl(targetLocation);
mClientContext.Load(newFile);
mClientContext.ExecuteQuery();
I'm a bit new to WinRT developing platform, and it's already driving me crazy (I'm a long-time .Net developer, and all those removed APIs are quite annoying)
I'm experiencing a problem while zipping all files present in the Windows.Storage.ApplicationData.Current.TemporaryFolder
Here is my current code (VB.Net, based on MSDN code, and "file" is the zip file I'll put all my files into) :
Using zipMemoryStream As New MemoryStream()
Using zipArchive As New Compression.ZipArchive(zipMemoryStream, Compression.ZipArchiveMode.Create)
For Each fileToCompress As Windows.Storage.StorageFile In (Await Windows.Storage.ApplicationData.Current.TemporaryFolder.GetFilesAsync())
Dim buffer As Byte() = WindowsRuntimeBufferExtensions.ToArray(Await Windows.Storage.FileIO.ReadBufferAsync(fileToCompress))
Dim entry As ZipArchiveEntry = zipArchive.CreateEntry(fileToCompress.Name)
Using entryStream As Stream = entry.Open()
Await entryStream.WriteAsync(buffer, 0, buffer.Length)
End Using
Next
End Using
Using zipStream As Windows.Storage.Streams.IRandomAccessStream = Await file.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite)
Using outstream As Stream = zipStream.AsStreamForWrite()
Dim buffer As Byte() = zipMemoryStream.ToArray()
outstream.Write(buffer, 0, buffer.Length)
outstream.Flush()
End Using
End Using
End Using
It builds well, but when I launch the code, I have the exception :
UnauthorizedAccessException : Access denied. (Exception de HRESULT : 0x80070005 (E_ACCESSDENIED))
On line : WindowsRuntimeBufferExtensions.ToArray(blahblah...
I'm wondering what is wrong. Any idea ?
Thanks in advance !
I rewrote your method in C# to try it out:
var file = await ApplicationData.Current.LocalFolder.CreateFileAsync("test.zip");
using (var zipMemoryStream = new MemoryStream())
{
using (var zipArchive = new System.IO.Compression.ZipArchive(zipMemoryStream, System.IO.Compression.ZipArchiveMode.Create))
{
foreach (var fileToCompress in (await ApplicationData.Current.TemporaryFolder.GetFilesAsync()))
{
var buffer = WindowsRuntimeBufferExtensions.ToArray(await FileIO.ReadBufferAsync(fileToCompress));
var entry = zipArchive.CreateEntry(fileToCompress.Name);
using (var entryStream = entry.Open())
{
await entryStream.WriteAsync(buffer, 0, buffer.Length);
}
}
}
using ( var zipStream = await file.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite))
{
using (var outstream = zipStream.AsStreamForWrite())
{
var buffer = zipMemoryStream.ToArray();
outstream.Write(buffer, 0, buffer.Length);
outstream.Flush();
}
}
}
It works flawlessly - it creates the zip file in local folder as expected. Since you get the exception in ToArray call, the reason could be that the file you're trying to open is already locked from somewhere else. If you are creating these files yourself or even only accessing them, make sure you're closing the streams.
To test this method you could manually create a folder inside temp folder, put a couple of files in it and then run the method on that folder (the files are in C:\Users\<Username>\AppData\Local\Packages\<PackageName>\TempState) just to exclude any other reason for error.
I've been trying to read a pre-built file with Car Maintenance tips, there's one in each line of my "Tips.txt" file. I've tried to follow around 4 or 5 different approaches but It's not working, it compiles but I get an exception. Here's what I've got:
using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
{
using (StreamReader sr = new StreamReader(store.OpenFile("Tips.txt", FileMode.Open, FileAccess.Read)))
{
string line;
while ((line = sr.ReadLine()) != null)
{
(App.Current as App).MyTips.Insert(new DoubleNode(line));
}
}
}
I'm getting this "Operation not permitted on IsolatedStorageFileStream", from the info inside the 2nd using statement. I tried with the build action of my "Tips.txt" set to resource, and content, yet I get the same result.
Thanks in advance.
Since you've added it to your project directory, you can't read it using Isolated Storage methods. There are various ways you can load the file. One way would be to set the text file's build type to Resource, then read it in as a stream:
//Replace 'MyProject' with the name of your XAP/Project
Stream txtStream = Application.GetResourceStream(new Uri("/MyProject;component/myTextFile.txt",
UriKind.Relative)).Stream;
using(StreamReader sr = new StreamReader(txtStream))
{
//your code
}
