28.5. Overloading WebMethods

In the object-oriented world of .NET, it is quite possible to use method overloading in the code you develop. A true object-oriented language has support for polymorphism, of which method overloading is a part. Method overloading enables you to have multiple methods that use the same name but have different signatures. With method overloading, one method can be called, but the call is routed to the appropriate method based on the full signature of the request. An example of standard method overloading is illustrated in the following code listing:

Public Function HelloWorld() As String
   Return "Hello"
End Function

Public Function HelloWorld(ByVal FirstName As String) As String
   Return "Hello " & FirstName
End Function
