asp.net mvc: make RedirectToAction(string, object)

2019-04-12 05:33发布

anybody knows how to make a method (I will put it in a extensions class) that will do the same as the mvc's RedirectToAction only using expressions (no magic strings).

So that instead of writing something like this:

 RedirectToAction("Detail", 
    new RouteValueDictionary { {"messageId", messageId}});

I would do like this:

this.RedirectToAction(x => x.Detail(messageId));

I tried and did something like this but I don't know how to add the parameters:

 public static RedirectToRouteResult RedirectToAction<T>(this T controller,
     Expression<Action<T>> expression)
 {
     return RedirectToAction(
        (expression.Body as MethodCallExpression).Method.Name
     );
 }
