The WebService method is called asynchronously!

The WebService method does not need to be modified, but uses an Asynchronous Method During the call. In this way, the speed will be faster in the loop.

Original method:

Using magweb.com. china_sms.www.MainServices sms = new using magweb.com. china_sms.www.MainServices (); // instantiate an object
String sSendRes = sms. massSend (); // call the method directly

Now you can change it to asynchronous call method: HotelMagWeb.com. china_sms.www.MainServices sms = new domains magweb.com. china_sms.www.MainServices (); // The same instantiation object
Sms. BeginmassSend (new AsyncCallback (MySMS), sms); // use the method starting with Begin to pass in a method (my name is MySMS)

// Implement real calls and results in this method!
Public static void MySMS (IAsyncResult iar)
{
Using magweb.com. china_sms.www.MainServices sms = (using magweb.com. china_sms.www.MainServices) iar. AsyncState;
String sSendRes = sms. EndmassSend (iar );
}
