c# - 获取客户端机器的IP地址

Question

我正在尝试使用 C# 获取客户端计算机的 IP 地址。我正在使用以下代码获取 IP 地址:

string IPAddress = HttpContext.Current.Request.UserHostAddress;

但它以编码格式给我响应，即 fe80::ed13:dee2:127e:1264%13

如何获取实际IP地址？任何遇到此问题的人都请分享一些想法。

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;
}

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
