摘要

如果你编写过许多ASP.NET程序，那么你可能花了很多时间将Url映射到物理磁盘上的某个位置。当你需要在服务器上保存文件，或者执行某些URL解析、或者将请求重新路由的时候，你都需要做这些工作。

这篇文章将要解释Request对象的一些属性，这些属性根据应用程序和当前请求来提供路径和url信息。

首先，这里有两张表来展示针对给出的请求路径，Request对象的相关属性的值。

由于某些我也不清楚的原因，Url.Fragment属性通常是空的，而不是包含"#fragment"的值。

请求路径: http://localhost:96/Cambia3/Temp/Test.aspx?q=item#fragment

Request.ApplicationPath:	/Cambia3
Request.CurrentExecutionFilePath:	/Cambia3/Temp/Test.aspx
Request.FilePath:	/Cambia3/Temp/Test.aspx
Request.Path:	/Cambia3/Temp/Test.aspx
Request.PathInfo:
Request.PhysicalApplicationPath:	D:\Inetpub\wwwroot\CambiaWeb\Cambia3\
Request.RawUrl:	/Cambia3/Temp/Test.aspx?query=arg
Request.Url.AbsolutePath:	/Cambia3/Temp/Test.aspx
Request.Url.AbsoluteUri:	http://localhost:96/Cambia3/Temp/Test.aspx?query=arg
Request.Url.Fragment:
Request.Url.Host:	localhost
Request.Url.Authority:	localhost:96
Request.Url.LocalPath:	/Cambia3/Temp/Test.aspx
Request.Url.PathAndQuery:	/Cambia3/Temp/Test.aspx?query=arg
Request.Url.Port:	96
Request.Url.Query:	?query=arg
Request.Url.Scheme:	http
Request.Url.Segments:	/ Cambia3/ Temp/ Test.aspx

请求的路径: http://localhost:96/Cambia3/Temp/Test.aspx/path/info?q=item#fragment

Request.ApplicationPath:	/Cambia3
Request.CurrentExecutionFilePath:	/Cambia3/Temp/Test.aspx
Request.FilePath:	/Cambia3/Temp/Test.aspx
Request.Path:	/Cambia3/Temp/Test.aspx/path/info
Request.PathInfo:	/path/info
Request.PhysicalApplicationPath:	D:\Inetpub\wwwroot\CambiaWeb\Cambia3\
Request.RawUrl:	/Cambia3/Temp/Test.aspx/path/info?query=arg
Request.Url.AbsolutePath:	/Cambia3/Temp/Test.aspx/path/info
Request.Url.AbsoluteUri:	http://localhost:96/Cambia3/Temp/Test.aspx/path/info?query=arg
Request.Url.Fragment:
Request.Url.Host:	localhost
Request.Url.LocalPath:	/Cambia3/Temp/Test.aspx/path/info
Request.Url.PathAndQuery:	/Cambia3/Temp/Test.aspx/path/info?query=arg
Request.Url.Port:	96
Request.Url.Query:	?query=arg
Request.Url.Scheme:	http
Request.Url.Segments:	/ Cambia3/ Temp/ Test.aspx/ path/ info

下面是我用C#写的一个方法，用来处理URL并且生成表格。你需要在aspx页面中加入一个ID为"lblOutput"的Label控件，然后使用这个方法。

     3    lblOutput.Text = "
