Beispiele

Das folgende Beispiel zeigt, wie eine ReceiveReply Aktivität verwendet wird. Eine Send Aktivität wird erstellt und zu einer Sequencehinzugefügt. Anschließend ReceiveReply wird der Sequence Aktivität eine Aktivität hinzugefügt, um die Antwort von der Send Aktivität zu erhalten.

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) }  
            }  
        }  
    };

    {  
       Body = new Sequence  
       {  
          Variables = { message, result },
