Examples

The following code example illustrates the use of this class.

using System;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Security.Permissions;
using System.Web.Services;
using System.Web.Services.Description;
using System.Web.Services.Discovery;
using System.Xml;
using System.Xml.Serialization;
