答
您将在客户端获得Web服务调用代码.下面的代码将有助于显示进度条.
You will have the web service call code at client side. Below code will help to display the progress bar.
myServiceReference = new myService.myServiceClient();
myServiceReference.GetUserCredentialsCompleted += (sender, args) =>
{
// Progress bar completed value
}
myServiceReference.GetMethodAsync(ID);
// Progress bar started value
