如果客户使用代理，又没有办法获取真实的ip??

帮你粘过来啦~~~string ClientIP;
if(FireWallLeap)
{
if(System.Web.HttpContext.Current.Request.ServerVariables["HTTP_VIA"]!=null)
{
ClientIP=System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
}
else
{
ClientIP=System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString();
}
}
else
{
ClientIP=System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString();
}
