如何在Win 10 UWP项目中找到本地IP地址 [英] How do I find the local IP address on a Win 10 UWP project

问题描述

我目前正在尝试将管理控制台应用程序移植到Win 10 UWP应用程序。我在使用以下控制台代码中的System.Net.Dns时遇到问题。

I am currently trying to port an administrative console application over to a Win 10 UWP app. I am having trouble with using the System.Net.Dns from the following console code.

如何获取设备IP

以下是我尝试移植的控制台应用程序代码。

Here is the console app code that I am trying to port over.

public static string GetIP4Address()
{
    string IP4Address = String.Empty;
    foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
    {
        if (IPA.AddressFamily == AddressFamily.InterNetwork)
        {
            IP4Address = IPA.ToString();
            break;
        }
    }
    return IP4Address;
}

推荐答案

您可以尝试这样：

private string GetLocalIp()
{
    var icp = NetworkInformation.GetInternetConnectionProfile();

    if (icp?.NetworkAdapter == null) return null;
    var hostname =
        NetworkInformation.GetHostNames()
            .SingleOrDefault(
                hn =>
                    hn.IPInformation?.NetworkAdapter != null && hn.IPInformation.NetworkAdapter.NetworkAdapterId
                    == icp.NetworkAdapter.NetworkAdapterId);

    // the ip address
    return hostname?.CanonicalName;
}

上面的答案也是正确的
