WebReferenceCollection Class

Describes a collection of WebReference objects.

Namespace:  System.Web.Services.Description
Assembly:  System.Web.Services (in System.Web.Services.dll)

public sealed class WebReferenceCollection : CollectionBase

Use this class to pass a collection of WebReference objects when invoking the static GenerateWebReferences method of the ServiceDescriptionImporter class.

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;
