Question

I am not getting any exception in the following code, however I also don’t see the file which is suppose to be uploaded to the server (in this case a localhost) – could someone please point out the mistake?

As an add on, I need a simple silverlight file uploader with a progress bar, but I am having a really hard time try using the ones on the codeplex, Does anyone here has a good one for SL4?

public FileStream MyFS { get; set; }

private void UploadFile()
{
    FileStream _data; // The file stream to be read
    _data = MyFS;
    string uploadUri;
    uploadUri = @"http://localhost/MyApplication/Upload/Images/testXRay.gif";

    byte[] fileContent = new byte[_data.Length]; // Read the contents of the stream into a byte array
    int dataLength = int.Parse(_data.Length.ToString());
    _data.Read(fileContent, 0, dataLength);

    WebClient wc = new WebClient();
    wc.OpenWriteCompleted += new OpenWriteCompletedEventHandler(wc_OpenWriteCompleted);
    Uri u = new Uri(uploadUri);
    wc.OpenWriteAsync(u, null, fileContent); // Upload the file to the server
}

void wc_OpenWriteCompleted(object sender, OpenWriteCompletedEventArgs e) // The upload completed
{
    if (e.Error == null)
    {
        // Upload completed without error
    }
}

Thanks,

You are trying to write to a server URL that is an image, not a service:

uploadUri = @"http://localhost/MyApplication/Upload/Images/testXRay.gif";
...
Uri u = new Uri(uploadUri);
wc.OpenWriteAsync(u, null, fileContent);

You can’t just write a file (via HTTP) to a webserver like that. The receiving URL needs to be a web service designed to accept the incoming byte stream.

I am sure there are better examples about, but try this link first.
