如何在Windows 10通用应用程序中的C#中获取本地主机名

问题描述

string machineName = System.Environment.MachineName;

此代码对我不起作用，错误代码"Environment"不包含"MachineName"的定义

This code doesn't work for me, error code 'Environment' does not contain a definition for 'MachineName'

我正在将Visual Studio 2015和Universal App与C#一起使用

I'm using Visual Studio 2015 and Universal App with C#

推荐答案

您需要使用 NetworkInformation.GetHostNames .

You need to use NetworkInformation.GetHostNames.

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

但是请注意，此方法将返回多个HostName.

But note that this method will return multiple HostNames.

在我的情况下，它返回四个HostName，其中DisplayName是 MyComputerName ， MyComputerName.local 和两个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很安全-

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 ?? "???";
