使用Route属性在Controller方法中获取控制器和动作名称

Question

我在控制器中定义了一个路由，

[Route("AboutUs/Profile")]
[Route("AboutUs/Organization")]
public ActionResult Contents()
{
    string _controller = RouteData.Route.GetRouteData(this.HttpContext).Values["controller"].ToString();
    string _action = RouteData.Route.GetRouteData(this.HttpContext).Values["action"].ToString(); 
}

但是_action == "Contents"，我怎样才能得到_action = "Profile"？

我试过了：

string _controller = this.ControllerContext.RouteData.Values["controller"].ToString();
string _action = this.ControllerContext.RouteData.Values["action"].ToString();

还有这个

string _controller = this.RouteData.Values["controller"].ToString();
string _action = this.RouteData.Values["_action"].ToString();

但所有这些都不起作用。

我编写了这段代码来记录操作：

public class PreviousPage
{
    public string Action { get; set; }
    public string Controller { get; set; }
    public object Parameters { get; set; }

    public PreviousPage() { PP(); }
    public PreviousPage(string action, string controller, object parameters)
    {
        Action = action;
        Controller = controller;
        Parameters = parameters;
    }

    public void PP()
    {
        var htpc = HttpContext.Current.Request.RequestContext.RouteData.Values;

        object controller;
        htpc.TryGetValue("controller", out controller);
        Controller = controller as string;

        object action;
        htpc.TryGetValue("action", out action);
        Action = action as string;

        object id;
        htpc.TryGetValue("id", out id);
        int q = HttpContext.Current.Request.RawUrl.IndexOf('?');
        if (q>-1)
            Parameters = HttpContext.Current.Request.RawUrl.Substring(q+1);
        else
            Parameters = id as string;
    }
}

这是为了掩饰，但稍作修改你就会到达那里。

编辑：

通过静态函数获取动作：

    public static string GetAction()
    {
        object action=null;
        HttpContext.Current.Request.RequestContext.RouteData.Values.TryGetValue("action", out action);
        return  action as string;
    }
