OperationMessageCollection Class

Represents a collection of OperationInput and OperationOutput messages related to an XML Web service. This class cannot be inherited.

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

public sealed class OperationMessageCollection : ServiceDescriptionBaseCollection

An instance of this class will be returned by the Messages property of the parent Operation. As such, it can have exactly two members, one an OperationInput and the other an OperationOutput.
