範例

下列程式碼範例示範如何設定此事件的事件處理常式。

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

備註

每次非同步資料上傳作業完成時，都會引發此事件。 非同步資料上傳會藉由呼叫 UploadDataAsync 方法來啟動。

UploadDataCompletedEventHandler是這個事件的委派。 類別 UploadDataCompletedEventArgs 會提供事件處理常式與事件資料。
