我要注册的时候能得到注册人的IP 代码如何加

Question

protected void Button1_Click(object sender, EventArgs e)
    {
        string Edittext = WebEditor1.Text;        string tempnewstitle = Request.Form["newstitle"].Trim();
        string temppublishertel = Request.Form["publishertel"].Trim();
        string temppublisher = Request.Form["publisher"].Trim();
        mySocut.ExecuteSql("Insert Into liyang(newstitle,userphone,username,newstext,publishtime) Values ('" + tempnewstitle + "','" + temppublishertel + "','" + temppublisher + "','" + Edittext + "','" + DateTime.Now + "')  ");
        Response.Write("<script>alert('新增成功！');location.href='rep.aspx';</script>");
    }

Answer 1

用request.serverviaribles["..."]
具体参数我忘了,网上有

Answer 2

Request.UserHostAddress
request.serverviaribles["REMOTE_ADDR"]

Answer 3

给你最详细的
public static string IP
        {
            get
            {
                string userIP;
                 HttpRequest Request = HttpContext.Current.Request;
                
                // 如果使用代理，获取真实IP
                if (Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != "")
                    userIP = Request.ServerVariables["REMOTE_ADDR"];
                else
                    userIP = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
                if (userIP == null || userIP == "")
                    userIP = Request.UserHostAddress;
                return userIP;
            }
        }

Answer 4

public static string IPAddressAll
        {
            get
            {
                string ip = HttpContext.Current.Request.UserHostAddress;
                string agentip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
                if (!string.IsNullOrEmpty(agentip))
                {
                    //有代理                    if (agentip.IndexOf(".") == -1)
                        agentip = null;
                    if (agentip != null)
                    {
                        if (agentip.IndexOf("unknow") != -1)
                            agentip = agentip.Replace("unknow", string.Empty);                        string[] temparyip = agentip.Replace(" ", string.Empty).Replace("'", string.Empty).Split(new char[] { ',', ';' });
                        //过滤代理格式中的非IP和内网IP
                        for (int i = 0; i < temparyip.Length; i++)
                        {
                            if (temparyip[i] != string.Empty && IsIPAddress(temparyip[i])

                            }
                        }
                    }
                }
                else
                {
                    agentip = null;
                }                return ip;
            }
        }
