ASP.NET中Request.ApplicationPath、Request.FilePath、Request.Path、.Request.MapPath

本文主要是介绍ASP.NET中Request.ApplicationPath、Request.FilePath、Request.Path、.Request.MapPath，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

ASP.NET中Request.ApplicationPath、Request.FilePath、Request.Path、.Request.MapPath

1.Request.ApplicationPath->当前应用的目录

2.Request.FilePath->对应于iis的虚拟目录
如 URL http://mockte.com/1/index.html/pathinfo
FilePath = /1/index.html

3.Request.Path->当前请求的虚拟路径
Path 是 FilePath 和 PathInfo 尾部的串联。例如 URL http://mockte.com/1/index.html/pathinfo
那么Path = /1/index.html/pathinfo

4.Request.MapPath(string url)->将url映射为iis上的虚拟目录
这个目录都是相对于application的根目录的
于Server.MapPath相比,不会包含类似c:/这样的路径
可以理解为是相对路径(对比的Server.MapPath就是绝对路径)

5.Server.MapPath(string url)->将url映射为服务器上的物理路径
例如 http://mockte.com/1/index.html 假设你的应用程序在c:/iis/MySite中
那么就是 c:/iis/MySite/1/index.html

6.底下这张表就是根据Browser Request 的网址相关的属性的用法
