asp.net mvc:将RedirectToAction(string，object)转换为RedirectToAction< Controller>(x => x.Detail(id)) [英] asp.net mvc: make RedirectToAction(string, object) into RedirectToAction<Controller>(x => x.Detail(id))

问题描述

任何人都知道如何制作一种方法(我将其放在扩展类中)，该方法仅使用表达式(无魔术字符串)才能与mvc的RedirectToAction相同.

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).

所以不要写这样的东西:

So that instead of writing something like this:

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

我会这样:

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

我尝试并做了类似的事情，但是我不知道如何添加参数:

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
     );
 }
