Send Send Send Send Class


An activity that sends a message to a service.

public ref class Send sealed : System::Activities::Activity
public sealed class Send : System.Activities.Activity
type Send = class
    inherit Activity
Public NotInheritable Class Send
Inherits Activity


The following example shows how to create a Send activity and add it to a workflow. The example also shows how to use ReceiveReply activity to receive the reply message.

Variable<string> message = new Variable<string>("message", "client");
Variable<string> result = new Variable<string> { Name = "result" };

Endpoint endpoint = new Endpoint
    AddressUri = new Uri(Common.Constants.ServiceBaseAddress),
    Binding = new BasicHttpBinding(),

Send requestEcho = new Send
    ServiceContractName = XName.Get("Echo", ""),
    Endpoint = endpoint,
    OperationName = "Echo",
    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>("Hello")
            new ReceiveReply
                Request = requestEcho,
                Content = new ReceiveParametersContent                            
                    Parameters = 
                        { "echo", new OutArgument<string>(result) }
            new WriteLine {
                Text = new InArgument<string>(result)
