[ContentPropertyAttribute("Content")]
public sealed class SendReply : Activity

Constructors

	Name	Description
	SendReply()	Initializes a new instance of the SendReply class.

Properties

	Name	Description
	Action	Gets or sets the value of the action header of the message.
	CacheId	Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.)
	Content	Gets or sets the content sent by the SendReply activity.
	CorrelationInitializers	Gets a collection of correlation initializers.
	DisplayName	Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from Activity.)
	Id	Gets an identifier that is unique in the scope of the workflow definition.(Inherited from Activity.)
	ImplementationVersion	Gets or sets the version of the implementation used.(Inherited from Activity.)
	PersistBeforeSend	Gets or sets a value that specifies whether the workflow service instance should be persisted before sending the message.
	Request	Gets or sets a reference to the Receive activity paired with this SendReply activity.

Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	FromOperationDescription(OperationDescription, IEnumerable<SendReply>)	Returns the send reply activity from the given contract operation description.
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	ShouldSerializeDisplayName()	Indicates whether the DisplayName property should be serialized.(Inherited from Activity.)
	ToString()	Returns a String that contains the Id and DisplayName of the Activity.(Inherited from Activity.)

Examples

The following example shows how to create a SendReply activity and add it to a workflow in code.

Variable<string> message = new Variable<string> { Name = "message" };
Variable<string> echo = new Variable<string> { Name = "echo" };
Receive receiveString = new Receive
{
    OperationName = "Echo",
    ServiceContractName = "Echo",
    CanCreateInstance = true,
    //parameters for receive
    Content = new ReceiveParametersContent
    {
        Parameters = 
        {
            {"message", new OutArgument<string>(message)}
        }
    }
};

Sequence workflow = new Sequence()
{
    Variables = { message, echo },
    Activities =
        {
            receiveString,
            new WriteLine
            {
                Text = new InArgument<string>(env =>("Message received: " + message.Get(env)))
            },
            new Assign<string>
            {
                Value = new InArgument<string>(env =>("<echo> " + message.Get(env))),
                To = new OutArgument<string>(echo)
            },                        
            //parameters for reply
            new SendReply
            {                           
                Request = receiveString,                            
                Content = new SendParametersContent
                {
                    Parameters =
                    {
                        { "echo", new InArgument<string>(echo) }
                    },
                }
            },
            new WriteLine
            {
                Text = new InArgument<string>(env =>("Message sent: " + echo.Get(env)))
            },
        },
};

service = new WorkflowService
{
    Name = "Echo",
    Body = workflow
};
