UploadDataCompletedEventArgs Class

Provides data for the UploadDataCompleted event.

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

'Declaration
Public Class UploadDataCompletedEventArgs _
	Inherits AsyncCompletedEventArgs
'Usage
Dim instance As UploadDataCompletedEventArgs

Instances of this class are passed to the UploadDataCompletedEventHandler.

The following code example demonstrates asynchronously uploading data.

Public Shared Sub UploadDataInBackground2(ByVal address As String)

			Dim client As WebClient = New WebClient()
			Dim text As String = "Time = 12:00am temperature = 50" 
			Dim data() As Byte = System.Text.Encoding.UTF8.GetBytes(text)
			Dim method As String = "POST" 

			AddHandler client.UploadDataCompleted, AddressOf UploadDataCallback2
			Dim uri as Uri = New Uri(address)
                        client.UploadDataAsync(uri, method, data)
		End Sub
void UploadDataInBackground2 (String* address)
{
    WebClient* client = new WebClient ();
    String* text = S"Time = 12:00am temperature = 50";
    Byte data[] = System::Text::Encoding::UTF8->GetBytes (text);
    String* method = S"POST";

    client->UploadDataCompleted += new UploadDataCompletedEventHandler (UploadDataCallback2);
    client->UploadDataAsync (address, method, data);
}

The following method is called when the upload completes.

Private Shared Sub UploadDataCallback2(ByVal sender As Object, ByVal e As UploadDataCompletedEventArgs)

    Dim data() As Byte = CType(e.Result, Byte())
    Dim reply As String = System.Text.Encoding.UTF8.GetString(data)

    Console.WriteLine(reply)
End Sub
void UploadDataCallback2 (Object* /*sender*/, UploadDataCompletedEventArgs* e)
{
    Byte data[] = dynamic_cast<Byte[]>(e->Result);
    String* reply = System::Text::Encoding::UTF8->GetString (data);

    Console::WriteLine (reply);
}
