How do I find the fully qualified hostname of my machine in C#? [duplicate]

Question

Ex : I want something like abc.hyd.mycompany.com. My requirement is to parse this name and initialize appropriate service.

using System.Net;  Dns.GetHostName() // doesn't return fully qualified name it just gives "abc"  

Answer 1

You may be able to get the whole DNS string like this:

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.
