c# - 使用 Route 属性在 Controller 方法中获取 Controller 和操作名称

Question

我在 Controller 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"？

我试过这个:

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();

但这一切都不起作用。

我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;
    }
}

这太过分了，但稍加修改就可以了。

编辑:

通过静态函数获取 Action :

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