How do I get the Ip address of the client machines?

string ip = "";
               string strHostName = "";
               strHostName = System.Net.Dns.GetHostName();
               IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName);
               IPAddress[] addr = ipEntry.AddressList;
               ip = addr[addr.Length - 1].ToString();

{
    string VisitorsIPAddr = string.Empty;
    if (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
    {
        VisitorsIPAddr = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
    }
    else if (HttpContext.Current.Request.UserHostAddress.Length != 0)
    {
        VisitorsIPAddr = HttpContext.Current.Request.UserHostAddress;

试试这个，

Try this,

protected string GetIPAddress()
{
    System.Web.HttpContext context = System.Web.HttpContext.Current;
    string ipAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

    if (!string.IsNullOrEmpty(ipAddress))
    {
        string[] addresses = ipAddress.Split(',');
        if (addresses.Length != 0)
        {
            return addresses[0];
        }
    }

    return context.Request.ServerVariables["REMOTE_ADDR"];
}
