asp.net获取URL和IP地址

HttpContext.Current.Request.Url.ToString() 并不可靠。

如果当前URL为
http://localhost/search.aspx?user=http://csharp.xdowns.com&tag=%BC%BC%CA%F5

通过HttpContext.Current.Request.Url.ToString()获取到的却是

http://localhost/search.aspxuser=http://csharp.xdowns.com&tag=¼¼Êõ


正确的方法是：HttpContext.Current.Request.Url.PathAndQuery

1、通过ASP.NET获取
如果测试的url地址是http://www.test.com/testweb/default.aspx, 结果如下：
Request.ApplicationPath:                /testweb
Request.CurrentExecutionFilePath:       /testweb/default.aspx
Request.FilePath:                       /testweb/default.aspx
Request.Path:                           /testweb/default.aspx
Request.PhysicalApplicationPath:         E:\WWW\testwebRequest.PhysicalPath:                    E:\WWW\testweb\default.aspx
Request.RawUrl:                         /testweb/default.aspx
Request.Url.AbsolutePath:               /testweb/default.aspx
Request.Url.AbsoluteUrl:                 http://www.test.com/testweb/default.aspx
Request.Url.Host:                        www.test.com
Request.Url.LocalPath:                  /testweb/default.aspx
