How do I get the local machine name in C#?

Question

How do I get the local machine name?

Answer 1

System.Environment.MachineName

Answer 2

You should be able to use System.Environment.MachineName for this. It is a property that returns a string containing the netBIOS name of the computer:

Answer 3

From link text

Four ways to get your local network/machine name:

string name = Environment.MachineName;
string name = System.Net.Dns.GetHostName();
string name = System.Windows.Forms.SystemInformation.ComputerName;
string name = System.Environment.GetEnvironmentVariable("COMPUTERNAME");

Answer 4

If you want the FQDN (fully qualified domain name) of the local computer, you can use

System.Net.Dns.GetHostEntry("localhost").HostName

The other methods will only return the local name, without any domain specific info. For instance, for the computer myComp.myDomain.com, the previous methods will return myComp, whereas the GetHostEntry method will return myComp.myDomain.com
