Examples

The following code example demonstrates asynchronously uploading a file.

// Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
void UploadFileInBackground2( String^ address, String^ fileName )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);

   client->UploadFileCompleted += 
     gcnew UploadFileCompletedEventHandler (UploadFileCallback2);
   
   // Specify a progress notification handler.
   client->UploadProgressChanged += 
       gcnew UploadProgressChangedEventHandler( UploadProgressCallback );
   client->UploadFileAsync( uri, "POST", fileName );
   Console::WriteLine( "File upload started." );
}


  // Sample call: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
  public static void UploadFileInBackground2 (string address, string fileName)
  {
      WebClient client = new WebClient ();
      Uri uri = new Uri(address);

      client.UploadFileCompleted += new UploadFileCompletedEventHandler (UploadFileCallback2);

// Specify a progress notification handler.
client.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressCallback);
      client.UploadFileAsync (uri, "POST", fileName);
      Console.WriteLine ("File upload started.");
  }

'  Sample call: UploadFileInBackground2("http:' www.contoso.com/fileUpload.aspx", "data.txt")
Public Shared Sub UploadFileInBackground2(ByVal address As String, ByVal fileName As String)

	Dim client As WebClient = New WebClient()
                      Dim uri as Uri =  New Uri(address)
	AddHandler client.UploadFileCompleted, AddressOf UploadFileCallback2

	'  Specify a progress notification handler.
	AddHandler client.UploadProgressChanged, AddressOf UploadProgressCallback
	client.UploadFileAsync(uri, "POST", fileName)
	Console.WriteLine("File upload started.")
End Sub

The following method is called when the upload completes.

void UploadFileCallback2( Object^ /*sender*/, UploadFileCompletedEventArgs^ e )
{
   String^ reply = System::Text::Encoding::UTF8->GetString( e->Result );
   Console::WriteLine( reply );
}


private static void UploadFileCallback2 (Object sender, UploadFileCompletedEventArgs e)
{
    string reply = System.Text.Encoding.UTF8.GetString (e.Result);
    Console.WriteLine (reply);
}

Private Shared Sub UploadFileCallback2(ByVal sender As Object, ByVal e As System.Net.UploadFileCompletedEventArgs)

    Dim reply As String = System.Text.Encoding.UTF8.GetString(e.Result)
    Console.WriteLine(reply)
End Sub
