重定向到 ASP MVC 中的 url

Question

我有一个操作结果方法，里面正在执行重定向（url）。我的问题是如何在执行重定向之前检查网址是否有效？

public ActionResult RedirectUser()
{
    var url = "/Cars/Model/1"; //this is the url

    // now i should check if the redirect return a 200 code (the url is valid) and if is valid I should redirect to that url, else i should redirect to "/Home/Index"

    if(this.Redirect(url))
    {
       return this.Redirect(url);
    }
    else
    {
       return this.RedirectToAction("Index", "Home");
    }

    return this.RedirectToAction("Index", "Home");
}

谁能帮我举个例子吗？我在谷歌上搜索，但找不到任何可以帮助我的东西。谢谢

尝试这个

public ActionResult RedirectUser()
{
    var url = "/Cars/Model/1"; //this is the url

     var controller = RouteData.Values["controller"].ToString();
 var action = RouteData.Values["action"].ToString();

    if(controller=="car"&& action=="Model")
    {
       return this.Redirect(url);
    }
    else
    {
       return this.RedirectToAction("Index", "Home");
    }

    return this.RedirectToAction("Index", "Home");
}
