public string HelloWorld() {
return "Hello World";
}
[WebMethod]
public int Add(int a, int b)
{
return a + b;
}

- no:1 shows the helloworld method and no:2 shows our mehod "Add" and no:3 shows the link to service discription of the web service
- When you click no:1 and no:2 as shown above you will get the web methods respectively
- Then we can click invoke button to check the web method. If there are any required field must be filled-these fields are the parameters of web method.
