如何获取本机主机名和IP地址,请各位帮忙!
ASP.NET C#
[解决办法]
可以很容易获得客户端的IP，本机不懂

请楼主讲述一下本机是指哪台机器，浏览器所在的机器还是服务器？
[解决办法]

[解决办法]
using System.Net;
Dns.GetHostName() // 主机名
Dns.GetHostAddresses(Dns.GetHostName())[0].ToString() //主机第一个IP
[解决办法]
楼上正解~~
[解决办法]
//得到用户IP
string ip = Request.ServerVariables[ "REMOTE_ADDR "].ToString();
if (ip == " ")
{
ip = Request.ServerVariables[ "HTTP_X_FORWARDED_FOR "].ToString();
}
[解决办法]
呵呵！来晚了，接分！

ls 正解。
