MessagePartCollection Class

Represents a collection of instances of the MessagePart class. This class cannot be inherited.

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

public ref class MessagePartCollection sealed : public ServiceDescriptionBaseCollection

The MessagePart class corresponds to a Web Services Description Language (WSDL) <part> element enclosed by the <message> element, which is in turn enclosed by the <definitions> root element. For more information about WSDL, see the specification at http://www.w3.org/TR/wsdl/.

The following example demonstrates the use of the methods and properties exposed by the MessagePartCollection class.
