asp.net mvc：将 RedirectToAction(string, object) 转换为 RedirectToAction(x => x.Detail(id))

任何人都知道如何创建一个方法（我将把它放在扩展类中），该方法将仅使用表达式（无魔术字符串）执行与 mvc 的 RedirectToAction 相同的操作。

因此，不要写这样的东西：

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

我会这样做：

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

我尝试并做了类似的事情，但我不知道如何添加参数：

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

原文

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
     );
 }
