Examples
The example below demonstrates a hit counter, incrementing the count every time a browser calls the XML Web service method.
<%@ WebService Language="C#" Class="Util"%>
using System.Web.Services;
public class Util: WebService {
[ WebMethod(Description="Application Hit Counter",EnableSession=false)]
public int HitCounter() {
if (Application["HitCounter"] == null) {
Application["HitCounter"] = 1;
}
else {
Application["HitCounter"] = ((int) Application["HitCounter"]) + 1;
}
return ((int) Application["HitCounter"]);
}
}
<%@ WebService Language="VB" Class="Util"%>
Imports System.Web.Services
Public Class Util
Inherits WebService
<WebMethod(Description := "Application Hit Counter", _
EnableSession := False)> _
Public Function HitCounter() As Integer
If Application("HitCounter") Is Nothing Then
Application("HitCounter") = 1
Else
Application("HitCounter") = CInt(Application("HitCounter")) + 1
End If
Return CInt(Application("HitCounter"))
End Function
End Class
Remarks
XML Web services can use both application state and session state. Application state is maintained across all sessions accessing an XML Web service regardless of whether session state is turned off for a method(by using the EnableSession property of the WebMethodAttribute).
