如何在C#.net中获取客户端的IP地址？

[jl_zqs]

请问，我如何在WebApplication中获取所连接的客户端的IP地址？

[Eddie005]

Request.UserHostAddress

[zxw17594840]

string IP = (Request.ServerVariables["HTTP_VIA"]!=null)?Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString():Request.ServerVariables["REMOTE_ADDR"].ToString();

[Eddie005]

string ipAddress = System.Web.HttpContext.Current.Request.UserHostAddress;

[aspnet_csharp]

先引用命名空间：using System.Net;
得到客户端IP地址：Request.ServerVariables["REMOTE_ADDR"]或Rqurest.UserHostAddress();
得到本机IP地址：Request.ServerVariables["local_addr"]或addr = new System.Net.IPAddress ( Dns.GetHostByName ( Dns.GetHostName ( ) ) .AddressList [0].Address ) ;

HttpBrowserCapabilities bc= Request.Browser;
Label3.Text=bc.Browser+" "+bc.Version;//得到浏览器版本
Label2.Text=bc.Platform;//得到操作系统
hostname=Dns.GetHostName();
IPHostEntry jj=Dns.GetHostByName(hostname);//得到IP
//IPAddress ip=Dns.Resolve(hostname);
Label1.Text=jj.AddressList[0].ToString();
