I am calling this from a silverlight app:
// docs at: http://developers.facebook.com/docs/reference/api/post
var client = new FacebookClient(_token);
dynamic parameters = new ExpandoObject();
parameters.message = title;
parameters.link = linkUrl;
parameters.picture = imageUrl;
parameters.name = name;
parameters.caption = promptTitle;
parameters.description = description;
parameters.privacy = new
{
value = "ALL_FRIENDS",
};
client.PostAsync("me/feed", parameters);
This generates the following error:

I am using asp.net-core-webapi and I am also using iTextSharp to create pdf in memory steam.
[Route("preview/{Id}")]
[System.Web.Http.HttpGet]
public async Task<IActionResult> PreviewSpecSheet(int Id)
{
FileStreamResult fsr;
Document document = new Document(PageSize.A4, 25, 25, 30, 30);
using (MemoryStream ms = new MemoryStream())
{
using (PdfWriter writer = PdfWriter.GetInstance(document, ms))
{
//PdfWriter writer = PdfWriter.GetInstance(document, ms);
document.Open();
//header Image

Edited after apply comment solution :
If I remove using its working fine but when I am using
document.Close();
writer.Close();
before fsr = File(ms, "application/pdf", "test.pdf"); its again same error and if I dont close the document and writer , downloaded pdf is in corrupt format , not able to open.
Okay, So I am able to figure this out what was the issue.
In original code issue was using block , as already mentioned in comments section.
But when I removed using still facing issue of stream closing when I close document and writer .
and the reason is The PdfWriter class may be closing your stream. Make sure to set the CloseStream property to false.
so I set writer CloseStream property to false , just after declare.
PdfWriter writer = PdfWriter.GetInstance(document, ms);
writer.CloseStream = false;
and its worked.
[Route("preview/{Id}")]
[System.Web.Http.HttpGet]
public async Task<IActionResult> PreviewSpecSheet(int Id)
{
FileStreamResult fsr;
Document document = new Document(PageSize.A4, 25, 25, 30, 30);
MemoryStream ms = new MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(document, ms);
writer.CloseStream = false;
document.Open();
//header Image
iTextSharp.text.Image headerImg = iTextSharp.text.Image.GetInstance("D:\\go2\\Pixelle\\specsheet\\pixservice\\assets\\header.jpg");
headerImg.SetAbsolutePosition(0, 750);
headerImg.ScaleAbsolute(500f, 100.00f);
document.Add(headerImg);
document.Close();
writer.Close();
ms.Position = 0;
fsr = File(ms, "application/pdf", "test.pdf");
return fsr;
}

All other values are captured except the file. I am getting a null value in the debugger. Why am I unable to upload a file into the database? Thanks in advance.
Firstly,default model binding system cannot bind file to byte[] properties.If you want to bind file to btye[],you can use ByteArrayModelBinder,here is an official link.
Also,if you don't mind to change the type of file_data,you can use
public IFormFile file_data { get; set; }
and then you can convert it to byte[] type with MemoryStream.Here is an official link about upload files in .net core.
I am trying to send a large file using FileStreamResult -
return new UnbufferedFileStreamResult(new FileStream(apiResponse.url, FileMode.Open, FileAccess.Read), "text/csv") { FileDownloadName = new FileInfo(apiResponse.url).Name };
The UnbufferedFileStreamResult is:
public class UnbufferedFileStreamResult : FileStreamResult {
public UnbufferedFileStreamResult(Stream fileStream, string contentType) : base(fileStream, contentType) {
}
public override void ExecuteResult(ActionContext context) {
context.HttpContext.DisableOutputBuffering();
base.ExecuteResult(context);
}
}
This seems to work for files up to a certain size, but if they get too big I get the following exception:
System.IO.IOException: Stream was too long.
at System.IO.MemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count)

So it appears that FileStreamResultExecutorBase is copying my file stream into a memory stream before it goes to the http output stream. My questions are 1) why is it doing this, 2) how can I prevent this behavior, and 3) are there implementations of results like FileStreamResult that can read directly from the input stream to the output stream without copying to memory first?
I have a WCF service application that is supposed to connect to another server X to retrieve data. When server X is configured with one-way SSL, the WCF service application is able to connect to it without problem. But when server X is configured with two-way SSL, the WCF service application will have problem connecting to it.
The WCF service application uses a self-signed certificate. This certificate was exported without private key into a .cer file, and imported into server X's trust store. The same exported certificate was used in the WCF service application's codes:
string URL = "https://11.205.112.49:5311/Ping";
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create(URL);
X509Certificate2 Certificate = new X509Certificate2("F:\\cert.cer");
Request.ClientCertificates.Add(Certificate);
Request.Method = "GET";
HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
The last line of the codes above will throw WebException with the following message:
The request was aborted: Could not create SSL/TLS secure channel.
The above error does not provide much details.
Help is appreciate.
Thanks in advance.
EDIT:
This is my entire program:
using System.Net;
using System.Security.Cryptography.X509Certificates;
using System.IO;

X509Certificate2 Certificate = new X509Certificate2("F:\\cert.pfx", "password");
Request.ClientCertificates.Add(Certificate);
Request.Method = "GET";
Console.WriteLine("Sending request.");
Response = (HttpWebResponse)Request.GetResponse();
Console.WriteLine("Request sent.");
}
catch (WebException webException)

Console.WriteLine("Web exception occurred: [{0}].", webException.Message);
Console.WriteLine(webException.StackTrace);

The problem is that you are missing private key. You are using only the certificate.
Either use pkcs#12 when loading certificate into X509Certificate2 class
X509Certificate2 Certificate = new X509Certificate2("F:\\cert.p12", "p12 password");
or load certificate from store
X509Store store = new X509Store("MY",StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
X509Certificate2Collection collection = (X509Certificate2Collection)store.Certificates;
X509Certificate2 certificate = collection.Find(...)[0];
store.Close();
