UploadFileCompletedEventArgs Class

Provides data for the UploadFileCompleted event.

Namespace:  System.Net
Assembly:  System (in System.dll)

public class UploadFileCompletedEventArgs : AsyncCompletedEventArgs

Instances of this class are passed to the UploadFileCompletedEventHandler.

The following code example demonstrates asynchronously uploading a file.

    // 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")
void UploadFileInBackground2 (String* address, String* fileName)
{
    WebClient* client = new WebClient ();

    client->UploadFileCompleted += new UploadFileCompletedEventHandler (UploadFileCallback2);

    // Specify a progress notification handler.
    client->UploadProgressChanged += new UploadProgressEventHandler(UploadProgressCallback);
    client->UploadFileAsync (address, S"POST", fileName);
    Console::WriteLine (S"File upload started.");
}

The following method is called when the upload completes.

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