asp.net获取URL和IP地址 (转)

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.PathAndQuery1、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 

2、通过JS获取

<table width=100% cellpadding=0 cellspacing=0 border=0 >

<script> 

thisURL = document.URL; 

thisHREF = document.location.href; 

thisSLoc = self.location.href; 

thisDLoc = document.location; 

strwrite = "<tr><td valign=top>thisURL: </td><td>[" + thisURL + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisHREF: </td><td>[" + thisHREF + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisSLoc: </td><td>[" + thisSLoc + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisDLoc: </td><td>[" + thisDLoc + "]</td></tr>" 

document.write( strwrite ); 

</script> 

thisDLoc = document.location; <BR>

thisURL = document.URL; <BR>

thisHREF = document.location.href; <BR>

thisSLoc = self.location.href;<BR>

<script> 

thisTLoc = top.location.href; 

thisPLoc = parent.document.location; 

thisTHost = top.location.hostname; 

thisHost = location.hostname; 

strwrite = "<tr><td valign=top>thisTLoc: </td><td>[" + thisTLoc + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisPLoc: </td><td>[" + thisPLoc + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisTHost: </td><td>[" + thisTHost + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisHost: </td><td>[" + thisHost + "]</td></tr>" 

document.write( strwrite ); 

</script> 

thisTLoc = top.location.href; <BR>

thisPLoc = parent.document.location; <BR>

thisTHost = top.location.hostname; <BR>

thisHost = location.hostname;<BR>

<script> 

tmpHPage = thisHREF.split( "/" ); 

thisHPage = tmpHPage[ tmpHPage.length-1 ]; 

tmpUPage = thisURL.split( "/" ); 

thisUPage = tmpUPage[ tmpUPage.length-1 ]; 

strwrite = "<tr><td valign=top>thisHPage: </td><td>[" + thisHPage + "]</td></tr>" 

strwrite += "<tr><td valign=top>thisUPage: </td><td>[" + thisUPage + "]</td></tr>" 

document.write( strwrite ); 

</script><tr><td>

获取IP
1、ASP.NET中获取

获取服务器的IP地址： 
using System.Net; 

string myIP,myMac;
System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList; 
if ( addressList.Length>1) 
>
