Question

我正在撰写自定义Route课程，然后使用return RedirectToRoute("MyRouteName")。

我怎么知道路线类中特别要求我自己的路线？

public bool IsRouteRequested()
{}

true会返回RedirecToRoute("MyRoute")而false会返回RedirectToAction("SomeAction", "SomeController")。

是否还可以检测是否从区域内调用RedirectToAction？

也许你服务，我不太喜欢，但这是我唯一能想到的：

public static class RedirectToRouteResultExtensions
{
    private static IDictionary<RedirectToRouteResult, bool> typeRoute;

    public static RedirectToRouteResult SetRouteRequested(this RedirectToRouteResult redirectToRouteResult, bool value)
    {
        if (typeRoute == null)
        {
            typeRoute = new Dictionary<RedirectToRouteResult, bool>();
        }

        typeRoute[redirectToRouteResult] = value;

        return redirectToRouteResult;
    }

    public static bool IsRouteRequested(this RedirectToRouteResult redirectToRouteResult)
    {
        if (typeRoute == null)
        {
            return false;
        }

        return typeRoute.ContainsKey(redirectToRouteResult)
                    ? typeRoute[redirectToRouteResult]
                    : false;
    }
}

示例：

return RedirectToRoute("MyRouteName").SetRouteRequested(true);

return RedirectToAction("SomeAction", "SomeController");

*编辑解决方案II *

在return RedirectToRoute("MyRouteName")之前，您可以在回复标题中添加信息：

HttpContext.Response.Headers.Add("CustomRoute", "1");
return RedirectToRoute("MyRouteName");

...

public bool IsRouteRequested()
{
   if (HttpContext.Response.Headers["CustomRoute"] != null &&
       HttpContext.Response.Headers["CustomRoute"] == "1")
       return true;  

   return false;

}

您可以像这样定义路线值

return RedirectToRoute("myRoute", new { myVal = "val" });

然后检查它是否可用于GetVirtualPath

中的ex

public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
         if(values["myVal"] != null)....

如何知道所要求的路线
