Příklady

Následující příklad kódu ukazuje nastavení obslužné rutiny události pro tuto událost.

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

Poznámky

Tato událost se vyvolá pokaždé, když se dokončí asynchronní operace nahrávání dat. Asynchronní nahrávání dat se spouští voláním UploadDataAsync metod.

Delegátem UploadDataCompletedEventHandler této události je. Třída UploadDataCompletedEventArgs poskytuje obslužnou rutinu události s daty události.
