CreatedAtRoute routing to different controller

Question

I\'m creating a new webapi using attribute routing to create a nested route as so:

    // PUT: api/Channels/5/Messages
    [ResponseType(typeof(void))]
    [

Late to the party but an alternative answer. If the action you are routing to also uses attribute routing, you can give the route a name and pass that in to the CreatedAtRoute method. This is done by setting a Name property on the Route. Following your post example, consider the following action.

// GET: api/Messages/5
[Route("api/messages/{id}", Name="GetMessage")]
public async Task GetMessage(int id)
{
    // get the message
}

Note that the Name property on the route attribute, [Route("api/messages/{id}", Name="GetMessage")], is set to "GetMessage". By doing this we can call the CreatedAtRoute method from the PostChannelMessage action and pass in the route name like so:

return CreatedAtRoute("GetMessage", new { id = message.Id }, message);

This is a scenario I encountered and my searching led here so thought I would post this alternative answer in case it helps anyone else.
