Action Parameter Naming

Question

Using the default route provided, I'm forced to name my parameters "id". That's fine for a lot of my Controller Actions, but I want to use some better variable naming in certain places. Is there some sort of attribute I can use so that I can have more meaningful variable names in my action signatures?

// Default Route:
routes.MapRoute(
  "Default",                                              // Route name
  "{controller}/{action}/{id}",                           // URL with parameters
  new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
);

// Action Signature:
public ActionResult ByAlias(string alias)
{
  // Because the route specifies "id" and this action takes an "alias", nothing is bound
}

Answer 1

Use the [Bind] attribute:

public ActionResult ByAlias([Bind(Prefix = "id")] string alias) {
    // your code here
}

Answer 2

This still works, your query string will just look like "/Controller/ByAlias?alias=something".
