OperationInput Class

Defines the specifications for input messages received by the XML Web service. This class cannot be inherited.

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

public ref class OperationInput sealed : public OperationMessage

Exactly one instance of this class is a member of the Messages property of the parent Operation instance.

The OperationInput class corresponds to the Web Services Description Language (WSDL) input element enclosed by the operation element that is in turn enclosed by the portType element. For more information about WSDL, see the specification at
