您需要使用 NetworkInformation.GetHostNames.

You need to use NetworkInformation.GetHostNames.

var hostNames = Windows.Networking.Connectivity.NetworkInformation.GetHostNames();

但是注意这个方法会返回多个HostName.

But note that this method will return multiple HostNames.

就我而言，它返回四个 HostName，其中 DisplayName 是 MyComputerName、MyComputerName.local加上两个 IP 地址.

In my case, it returns four HostNames of which DisplayNames are MyComputerName, MyComputerName.local plus two IP addresses.

所以我想这样做可能是安全的 -

So I guess it's probably safe to do -

using Windows.Networking;
using Windows.Networking.Connectivity;


var hostNames = NetworkInformation.GetHostNames();
var hostName = hostNames.FirstOrDefault(name => name.Type == HostNameType.DomainName)?.DisplayName ?? "???";
