How do I find the fully qualified hostname of my machine in C#?
提问by user21246
Ex : I want something like abc.hyd.mycompany.com. My requirement is to parse this name and initialize appropriate service.
例如：我想要像 abc.hyd.mycompany.com 这样的东西。我的要求是解析这个名称并初始化相应的服务。
using System.Net;
Dns.GetHostName() // doesn't return fully qualified name it just gives "abc"

You may be able to get the whole DNS string like this:
您可以像这样获取整个 DNS 字符串：
System.Net.Dns.GetHostEntry("").HostName
We don't have full fledged DNS names where I work, but it does give me a three level faux domain name instead of just the hostname.
我们在我工作的地方没有成熟的 DNS 名称，但它确实给了我一个三级假域名，而不仅仅是主机名。

If the above doesn't work, you can also try retrieving it from the environment:
如果上述方法不起作用，您还可以尝试从环境中检索它：
var dnsName = new StringBuilder();
dnsName.Append(Environment.GetEnvironmentVariable("COMPUTERNAME")).Append(".");
dnsName.Append(Environment.GetEnvironmentVariable("USERDNSDOMAIN"));

I used this very similar method:
我使用了这个非常相似的方法：
var serverName = System.Environment.MachineName; //host name sans domain
var fqhn = System.Net.Dns.GetHostEntry(serverName).HostName; //fully qualified hostname
