Operation Class

Provides an abstract definition of an action supported 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 sealed class Operation : NamedItem
public final class Operation extends NamedItem
public final class Operation extends NamedItem
Not applicable.

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.

using System;
using System.Web.Services.Description;
using System.Collections;
using System.Xml;

class MyOperationClass
{
   public static void Main()
   {
      ServiceDescription myDescription = ServiceDescription.Read("Operation_5_Input_CS.wsdl");
      // Create a 'PortType' object.
      PortType myPortType = new PortType();
      myPortType.Name = "OperationServiceHttpPost";
      Operation myOperation = CreateOperation
                         ("AddNumbers","s0:AddNumbersHttpPostIn","s0:AddNumbersHttpPostOut");    
      myPortType.Operations.Add(myOperation);
      // Get the PortType of the Operation. 
      PortType myPort = 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_CS.wsdl");
      Console.WriteLine("WSDL file with name 'Operation_5_Output_CS.wsdl' file created Successfully");
   }
   public static Operation CreateOperation(string myOperationName,string myInputMesg,string myOutputMesg)
   {
      // Create an Operation.
      Operation myOperation = new Operation();
      myOperation.Name = myOperationName;
      OperationMessage myInput = (OperationMessage)new OperationInput();
      myInput.Message =  new XmlQualifiedName(myInputMesg);
      OperationMessage myOutput = (OperationMessage)new OperationOutput();
      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;
   }
