Examples

In the example below the method GetMachineName can be remotely called across the Web, because it has a WebMethodAttribute. GetUserName cannot be called remotely, because it does not have a WebMethodAttribute, even though it is public.

<%@ WebService Language="C#" Class="Util"%>
    using System;
    using System.Web.Services;
    public class Util: WebService {
       public string GetUserName() {
          return User.Identity.Name;
       }
    
       [ WebMethod(Description="Obtains the Server Machine Name",
       EnableSession=true)]
       public string GetMachineName() {
          return Server.MachineName;
       }
    }

<%@ WebService Language="VB" Class="Util"%>

Imports System
Imports System.Web.Services

Public Class Util
    Inherits WebService
    
    Public Function GetUserName() As String
        Return User.Identity.Name
    End Function    
    
    <WebMethod(Description := "Obtains the Server Machine Name", _
        EnableSession := True)> _
    Public Function GetMachineName() As String
        
        Return Server.MachineName
    End Function
End Class

Remarks

Methods within a class that have this attribute set are called XML Web service methods. The method and class must be public and running inside an ASP.NET Web application.
