   Console::WriteLine( reply );
}

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

Private Shared Sub UploadFileCallback2(ByVal sender As Object, ByVal e As System.Net.UploadFileCompletedEventArgs)

    Console.WriteLine(reply)
End Sub

注解

应检查 Error 和 Cancelled 属性以确定上传是否完成。 Error如果属性的值为 Exception 对象或Cancelled属性的值为 true，则异步操作未正确完成，Result并且该属性的值将无效。
