推荐答案

尝试此功能:

Try this function:

public static string getclientIP()
{
    string result= string.Empty;
    string ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (!string.IsNullOrEmpty(ip))
    {
        string[] ipRange = ip.Split(',');
        int le = ipRange.Length - 1;
        result = ipRange[0];
    }
    else
    {
        result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
    }

    return result;
}

尝试这个

protected void ip_addr()
    {
        string sIPAddress = null;
        sIPAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
        if (string.IsNullOrEmpty(sIPAddress))
            sIPAddress =Request.ServerVariables["REMOTE_ADDR"];

        SqlConnection con = new SqlConnection(conn);
        try
        {
            con.Open();
            string str = "insert into IPADDR_LOGIN(ipaddr,date_time,uname) values('" + Convert.ToString(sIPAddress) + "','" + Convert.ToString(DateTime.Now) + "','" + txt_usr.Text.ToString().Trim() + "')";
            SqlCommand cmd = new SqlCommand(str, con);
            cmd.ExecuteNonQuery();
        }
        finally
        {
            con.Close();
        }
    }
