The Operation class corresponds to the Web Services Description Language (WSDL) operation element enclosed by the portType element. For more information about WSDL, see the specification at http://www.w3.org/TR/wsdl/.
The following example demonstrates a typical use of the Operation class. The example takes a ServiceDescription that does not have a PortType that supports the HTTP POST protocol. It adds a PortType instance that supports POST, and writes out a new WSDL contract.
Imports System Imports System.Web.Services.Description Imports System.Collections Imports System.Xml Class MyOperationClass Public Shared Sub Main() Dim myDescription As ServiceDescription = ServiceDescription.Read("Operation_5_Input_VB.wsdl") ' Create a 'PortType' object. Dim myPortType As New PortType() myPortType.Name = "OperationServiceHttpPost" Dim myOperation As Operation = CreateOperation("AddNumbers", "s0:AddNumbersHttpPostIn", _ "s0:AddNumbersHttpPostOut") myPortType.Operations.Add(myOperation) ' Get the PortType of the Operation. Dim myPort As PortType = myOperation.PortType Console.WriteLine( _ "The port type of the operation is: " & myPort.Name) ' Add the 'PortType's to 'PortTypeCollection' of 'ServiceDescription'. myDescription.PortTypes.Add(myPortType) ' Write the 'ServiceDescription' as a WSDL file. myDescription.Write("Operation_5_Output_VB.wsdl") Console.WriteLine("WSDL file with name 'Operation_5_Output_VB.wsdl'" + _ "file created Successfully") End Sub 'Main Public Shared Function CreateOperation(myOperationName As String, myInputMesg As String, _ myOutputMesg As String) As Operation ' Create an Operation. Dim myOperation As New Operation() myOperation.Name = myOperationName Dim myInput As OperationMessage = _ CType(New OperationInput(), OperationMessage) myInput.Message = New XmlQualifiedName(myInputMesg) Dim myOutput As OperationMessage = _ CType(New OperationOutput(), OperationMessage) myOutput.Message = New XmlQualifiedName(myOutputMesg) ' Add messages to the OperationMessageCollection. myOperation.Messages.Add(myInput) myOperation.Messages.Add(myOutput) Console.WriteLine("Operation name is: " & myOperation.Name) Return myOperation End Function 'CreateOperation End Class 'MyOperationClass
