How do I get the local machine name?
C# Solutions
Solution 1 - C#
System.Environment.MachineName
It works unless a machine name has more than 15 characters.

From source
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");

Solution 3 - C#
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:

Solution 4 - C#
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
Solution 5 - C#
My computer name is more than 15 chars, so i use hostname.exe to get full length name:
Process proc = new Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.FileName = "c:/windows/system32/hostname.exe";
proc.Start();
var hostName = proc.StandardOutput.ReadLine();
