Question

I have created an Action in my Home Controller which accepts a text:

 public class HomeController : Controller
    {
       public string DisplayText(string text)
        {
            return text;
        }
    }

I can call this Action, using the below url by passing the text parameter as a query string:

http://localhost:4574/Home/DisplayText?text=some text

However, I’d like to be able to call this using the below style:

http://localhost:4574/Home/DisplayText/some text

Therefore without specifying the parameter name (“text”);

How would that be possible?

Another example to explain it more clearly is as below

public string Add(string a, string b)
        {
            return (int.Parse(a) + int.Parse(b)).ToString();
        }

I can call it using:

http://localhost:4574/Home/Add?a=2&b=3

but how to call it in a RESTFul way? e.g. (http://localhost:4574/Home/Add/2/3)

You could define a route:

routes.MapRoute(
    "MyRoute",
    "{controller}/{action}/{a}/{b}",
    new { controller = "Home", action = "Add" },
    // it's always a good idea to define route constraints
    // in this case we are constraining the a and b parameters to numbers only
    new { a = @"\d+", b = @"\d+" } 
);

and then:

public ActionResult Add(int a, int b)
{
    return Content(string.Format("The result of {0}+{1}={2}", a, b, a + b));
}
