URL的获取很简单，ASP.NET通用：【1】获取 完整url （协议名+域名+虚拟目录名+文件名+参数）
string url=Request.Url.ToString();
【2】获取 虚拟目录名+页面名+参数：
string url=Request.RawUrl;(或 string url=Request.Url.PathAndQuery;)【3】获取 虚拟目录名+页面名：string url=HttpContext.Current.Request.Url.AbsolutePath;(或 string url= HttpContext.Current.Request.Path;)
【4】获取 域名：string url=HttpContext.Current.Request.Url.Host;
【5】获取 参数：string url= HttpContext.Current.Request.Url.Query;
【6】获取 端口：Request.Url.Port
二、当前controller、action的获取RouteData.Route.GetRouteData(this.HttpContext).Values["controller"]RouteData.Route.GetRouteData(this.HttpContext).Values["action"]或RouteData.Values["controller"]RouteData.Values["action"]如果在视图中可以用ViewContext.RouteData.Route.GetRouteData(this.Context).Values["controller"]ViewContext.RouteData.Route.GetRouteData(this.Context).Values["action"]或ViewContext.RouteData.Values["controller"]ViewContext.RouteData.Values["action"]
