How to get full host name in C#?

Question

I have tried by following by it just give me single name. I want full name. Ex. my system full name is "sys101.home.homeconsultancy.lan". Following code gives me just "sys101". I want full address "sys101.home.homeconsultancy.lan".

Here is my code:

string hostName = System.Net.Dns.GetHostName();

How can I get full system name?

What do you mean *"full host name"*? Do you mean the DNS name? — jww, Feb 18 '18 at 05:41

You can use System.Net.Dns.GetHostEntry:

var fullName = System.Net.Dns.GetHostEntry(string.Empty).HostName;

If an empty string is passed as the hostNameOrAddress argument, then this method returns the IPv4 and IPv6 addresses of the local host.
