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
};
The following example shows how to create a SendReply activity and add it to a workflow service in XAML.
