推荐答案

取决于你以后的IP地址。

如果你想在局域网上使用你的电脑的IP地址，那就很容易了：检索LAN的IP和MAC地址 [ ^ ]覆盖它，只需使用 GetIPAddress 方法并忽略其余部分。



如果你想要通过互联网向外界提供你的IP地址，那就更复杂了 - 它不是与您的PC有关，但与您的路由器有关，并且根本没有进入局域网。因此，您必须向外部服务询问价值： http://www.whatsmyip.org/ [ ^ ]是您可以提出的一种服务。

Depends which IP address you are after.
If you want the IP address of your PC on the LAN, then that is pretty easy: Retrieving IP and MAC addresses for a LAN[^] covers it, just use the GetIPAddress method and ignore the rest.

If you want your IP address that you present to the outside world via teh internet, then that is more complex - it isn''t related to your PC, but to your Router and doesn''t come into the LAN at all. So you have to ask an external service for the value: http://www.whatsmyip.org/[^] is one such service you can ask.

什么编程语言使用。



C＃.Net示例

尝试此功能获取您的公共IP

What programming language do use.

Example for C#.Net
Try this function to get your public IP

public string GetPublicIP()
{
    String direction = "";
    WebRequest request = WebRequest.Create("http://checkip.dyndns.org/");
    using (WebResponse response = request.GetResponse())
    using (StreamReader stream = new StreamReader(response.GetResponseStream()))
    {
        direction = stream.ReadToEnd();
    }

    //Search for the ip in the html
    int first = direction.IndexOf("Address: ") + 9;
    int last = direction.LastIndexOf("</body>");
    direction = direction.Substring(first, last - first);

    return direction;
}

并尝试使用此功能获取您的本地IP。

and try this function to get your local IP.

public string GetLocalIP(){
return Dns.GetHostEntry(Dns.GetHostName()).AddressList.FirstOrDefault(ip => ip.AddressFamily == AddressFamily.InterNetwork) ?? new IPAddress( new byte[] {127, 0, 0, 1} );
}

希望这会有所帮助。
