MimePartCollection Class

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

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

Public NotInheritable Class MimePartCollection _
	Inherits CollectionBase
Dim instance As MimePartCollection

Each MimePart within the collection represents an extensibility element added to a MimeMultipartRelatedBinding, and specifies the MIME type for a corresponding MessagePart.

For more information about specifying protocols for XML Web services, see [<topic://cpconbuildingaspnetwebservices>]. For more information about Web Services Description Language (WSDL), see the specification at

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