Question

我正在尝试使用C＃获取客户端计算机的IP地址。我使用以下代码获取IP地址：

string IPAddress = HttpContext.Current.Request.UserHostAddress;

但它以编码格式给我回复，fe80::ed13:dee2:127e:1264%13

如何获取实际的IP地址？任何人都面临这个问题请分享一些想法。

Answer 1

<强> C＃

string IPAddress = GetIPAddress();

public string GetIPAddress()
{
    IPHostEntry Host = default(IPHostEntry);
    string Hostname = null;
    Hostname = System.Environment.MachineName;
    Host = Dns.GetHostEntry(Hostname);
    foreach (IPAddress IP in Host.AddressList) {
        if (IP.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) {
            IPAddress = Convert.ToString(IP);
        }
    }
    return IPAddress;
}

<强> VB.net

Dim Host As IPHostEntry
Dim Hostname As String
Hostname = My.Computer.Name
Host = Dns.GetHostEntry(Hostname)
For Each IP As IPAddress In Host.AddressList
    If IP.AddressFamily = System.Net.Sockets.AddressFamily.InterNetwork Then
        IPAddress = Convert.ToString(IP)
    End If
    Next
Return IPAddress

希望这有帮助

Answer 2

private string GetUserIP()
 {
     return Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? Request.ServerVariables["REMOTE_ADDR"];    
 }

您可能会获得多个IP地址，因此可以将它们拆分为 -

private string GetUserIP()
    {
        string ipList = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

        if (!string.IsNullOrEmpty(ipList))
        {
            return ipList.Split(',')[0];
        }

        return Request.ServerVariables["REMOTE_ADDR"];
    }

Answer 3

尝试使用此

string ip=System.Net.Dns.GetHostEntry
               (System.Net.Dns.GetHostName()).AddressList.GetValue(0).ToString();

Answer 4

在我的项目中，需要获取本地PC IP。所以我用它请尝试以下代码

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