C#winform calls telecom kuanle's webservice to send short messages. Why is the return value always 0? Does vs2008 need any configuration?

If your parameters are useful account number, password, mobile phone number for sending SMS, and SMS content, is your API out of date? Why not set a breakpoint? I'll throw you a piece of my code for your reference. See if it works for you.

org . winic . service 2 . service 1 ws = new web application 1 . org . winic . service 2 . service 1()；

message manager message = new message manager()；

int userId = Convert。 ToInt32 (session ["userid"]);

Data table dt = message. get account(userId)；

String name = dt. Line [0]["MessageName"]. ToString()；

The string pwd = dt. Line [0]["MessagePwd"]. ToString()；

//Return a result, the first parameter is the mobile phone account number, the second parameter is the password, the third parameter is the mobile phone number, and the fourth parameter is the mobile phone content.

String result = ws. SendMessages (name, password, txtMoble. Text, short message. Text, "";

Switch (result)
