[.NET] 取得Server或Client IP

1. 取得Server IP語法：
using System.Net;
IPAddress ServerIP = IPAddress(Dns.GetHostByName(Dns.GetHostName()).AddressList[0].Address);
Response.Write("Server IP=" + ServerIP.ToString());

2. 取得Client IP
string strClientIP = Request.ServerVariables["REMOTE_ADDR"].ToString();
string strClientIP = Request.UserHostAddress;
//使用代理伺服器
string strClientIP = Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
