我正在做一个BBS，就是有人登陆，我就获取他的IP，用IPAddress该如何做呢？谢谢高手指点

public static string GetRealIP()
{
string ip;
try
{
HttpRequest request = HttpContext.Current.Request;

if (request.ServerVariables["HTTP_VIA"] != null)
{
ip = request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString().Split(',')[0].Trim();
}
else
{
ip = request.UserHostAddress;
}
}
catch (Exception e)
{
throw e;
}

return ip;
}
