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

'Declaration
Public NotInheritable Class OperationMessageCollection
	Inherits ServiceDescriptionBaseCollection
'Usage
Dim instance As OperationMessageCollection

public final class OperationMessageCollection extends ServiceDescriptionBaseCollection
public final class OperationMessageCollection extends ServiceDescriptionBaseCollection
