Examples

The following example shows how to use a ReceiveReply activity. A Send activity is created and added to a Sequence. A ReceiveReply activity is then added to the Sequence to receive the reply from the Send activity.

static void CreateClientWorkflow()  
{  
   Variable<string> message = new Variable<string>("message", "Hello!");  
   Variable<string> result = new Variable<string> { Name = "result" };  

   Endpoint endpoint = new Endpoint  
   {  
      AddressUri = new Uri(Microsoft.Samples.WorkflowServicesSamples.Common.Constants.ServiceBaseAddress), Binding = new BasicHttpBinding(),  
   };  

   Send requestEcho = new Send  
   {  
      ServiceContractName = XName.Get("Echo", "http://tempuri.org/"),  
                Endpoint = endpoint,  
                OperationName = "Echo",  
      //parameters for send  
      Content = new SendParametersContent  
      {  
         Parameters =   
            {   
               { "message", new InArgument<string>(message) }  
            }  
        }  
    };  
    workflow = new CorrelationScope  
    {  
       Body = new Sequence  
       {  
          Variables = { message, result },  
                    Activities =  
                    {  
                        new WriteLine {  
                            Text = new InArgument<string>("Client is ready!")  
                        },  
                        requestEcho,  

                        new WriteLine {  
                            Text = new InArgument<string>("Message sent: Hello!")  
                        },  

                        new ReceiveReply  
                        {  
                            Request = requestEcho,  
                            //parameters for the reply  
                            Content = new ReceiveParametersContent                              
                            {  
                                Parameters =   
                                {  
                                    { "echo", new OutArgument<string>(result) }  
                                }  
                            }  
                        },                                                  
                        new WriteLine {  
                            Text = new InArgument<string>(env => "Message received: "+result.Get(env))  
                        }  
                    }  
                }  
            };  
        }
