WebClient.UploadDataCompleted WebClient.UploadDataCompleted WebClient.UploadDataCompleted WebClient.UploadDataCompleted Event


Occurs when an asynchronous data-upload operation completes.

 event System::Net::UploadDataCompletedEventHandler ^ UploadDataCompleted;
public event System.Net.UploadDataCompletedEventHandler UploadDataCompleted;
member this.UploadDataCompleted : System.Net.UploadDataCompletedEventHandler 
Public Event UploadDataCompleted As UploadDataCompletedEventHandler 


The following code example demonstrates setting an event handler for this event.

void UploadDataInBackground3( String^ address )
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);
   String^ text = "Time = 12:00am temperature = 50";
   array<Byte>^data = System::Text::Encoding::UTF8->GetBytes( text );

   client->UploadDataCompleted += gcnew UploadDataCompletedEventHandler( UploadDataCallback3 );
   client->UploadDataAsync( uri, data );

public static void UploadDataInBackground3 (string address)
    WebClient client = new WebClient ();
    Uri uri = new Uri(address);
    string text = "Time = 12:00am temperature = 50";
    byte[] data = System.Text.Encoding.UTF8.GetBytes (text);

    client.UploadDataCompleted += new UploadDataCompletedEventHandler (UploadDataCallback3);
    client.UploadDataAsync (uri, data);

Public Shared Sub UploadDataInBackground3(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)
    AddHandler client.UploadDataCompleted, AddressOf UploadDataCallback3
                Dim uri as Uri = New Uri(address)
    client.UploadDataAsync(uri, data)
End Sub


This event is raised each time an asynchronous data upload operation completes. Asynchronous data uploads are started by calling the UploadDataAsync methods.

The UploadDataCompletedEventHandler is the delegate for this event. The UploadDataCompletedEventArgs class provides the event handler with event data.
