LogicalMethodInfo Class

Represents the attributes and metadata for an XML Web service method. This class cannot be inherited.

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

'Declaration
Public NotInheritable Class LogicalMethodInfo
'Usage
Dim instance As LogicalMethodInfo

LogicalMethodInfo is used primarily by a SOAP extension to interrogate the details of the XML Web service method with which the SOAP extension is configured to run. Depending on how the SOAP extension is configured, it can find out details about the XML Web service method in the GetInitializer method of SoapExtension that takes a LogicalMethodInfo. The LogicalMethodInfo provides details such as the XML Web service method's parameters by accessing the Parameters property and any custom attributes applied to the XML Web service method using the GetCustomAttributes property.

For more details on SOAP extensions see the SoapExtension class or [<topic://cpconAlteringSOAPMessageUsingSOAPExtensions>].
