Files uploaded but not appearing on server - asp.net-web-api2

Question

I use the code stated here to upload files through a webapi http://bartwullems.blogspot.pe/2013/03/web-api-file-upload-set-filename.html. I also made the following api to list all the files I have :
[HttpPost]
[Route("sharepoint/imageBrowser/listFiles")]
[SharePointContextFilter]
public async Task<HttpResponseMessage> Read()
{
string pathImages = HttpContext.Current.Server.MapPath("~/Content/images");
DirectoryInfo d = new DirectoryInfo(pathImages);//Assuming Test is your Folder
FileInfo[] Files = d.GetFiles(); //Getting Text files
List<object> lst = new List<object>();
foreach (FileInfo f in Files)
{
lst.Add(new
{
name = f.Name,
type = "f",
size = f.Length
});
}
return Request.CreateResponse(HttpStatusCode.OK, lst);
}
When calling this api, all the files uploaded are listed. But when I go to azure I dont see any of them (Content.png is a file I manually uploaded to azure)
Why are the files listed if they dont appear on azure.

According to your description, I suggest you could firstly use azure kudu console to locate the right folder in the azure web portal to see the image file.
Open kudu console:
In the kudu click the debug console and locate the site\wwwroot\yourfilefolder
If you find your file is still doesn't upload successfully, I guess there maybe something wrong with your upload codes. I suggest you could try below codes.
Notice: You need add image folder in the wwwort folder.
{
public class UploadingController : ApiController
{
public async Task<HttpResponseMessage> PostFile()
{
// Check if the request contains multipart/form-data.
if (!Request.Content.IsMimeMultipartContent())
{
throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
}
string root = Environment.GetEnvironmentVariable("HOME").ToString() + "\\site\\wwwroot\\images";
//string root = HttpContext.Current.Server.MapPath("~/images");
var provider = new FilenameMultipartFormDataStreamProvider(root);
try
{
StringBuilder sb = new StringBuilder(); // Holds the response body
// Read the form data and return an async task.
await Request.Content.ReadAsMultipartAsync(provider);
// This illustrates how to get the form data.
foreach (var key in provider.FormData.AllKeys)
{
foreach (var val in provider.FormData.GetValues(key))
{
sb.Append(string.Format("{0}: {1}\n", key, val));
}
}
// This illustrates how to get the file names for uploaded files.
foreach (var file in provider.FileData)
{
FileInfo fileInfo = new FileInfo(file.LocalFileName);
sb.Append(string.Format("Uploaded file: {0} ({1} bytes)\n", fileInfo.Name, fileInfo.Length));
}
return new HttpResponseMessage()
{
Content = new StringContent(sb.ToString())
};
}
catch (System.Exception e)
{
return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e);
}
}
}
public class FilenameMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
public FilenameMultipartFormDataStreamProvider(string path) : base(path)
{
}
public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
{
var name = !string.IsNullOrWhiteSpace(headers.ContentDisposition.FileName) ? headers.ContentDisposition.FileName : Guid.NewGuid().ToString();
return name.Replace("\"", string.Empty);
}
}
}
Result:
