Remarks

This collection can either contain instances of classes deriving from ServiceDescriptionFormatExtension, or instances of the XmlElement class. In a derived class, ServiceDescriptionFormatExtension class allows users to define extensibility elements in addition to those defined in the Web Services Description Language (WSDL) specification. Use these in your ServiceDescriptionFormatExtensionCollection if you know in advance the type of extensibility element you want to make. Use an XmlElement when you do not know the format of an element in advance.

Constructors

ServiceDescriptionFormatExtensionCollection(Object)

Initializes a new instance of the ServiceDescriptionFormatExtensionCollection class.

IndexOf(Object)	Searches for the specified ServiceDescriptionFormatExtension and returns the zero-based index of the first instance with the collection.
Insert(Int32, Object)	Adds the specified ServiceDescriptionFormatExtension to the ServiceDescriptionFormatExtensionCollection at the specified zero-based index.
IsHandled(Object)	Returns a value indicating whether the specified object is used by the import process when the extensibility element is imported into the XML Web service.
IsRequired(Object)	Returns a value indicating whether the specified object is necessary for the operation of the XML Web service.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnClear()	Clears the contents of the ServiceDescriptionBaseCollection instance. (Inherited from ServiceDescriptionBaseCollection)
