sniff the name of your computer in C#

In C# System.Net.Dns.GetHostName() returns the "DNS host name of the local computer" which may be thought of less verbosely as "the computer name" and should be the same thing you get by typing hostname at a command prompt. A use of System.Net.Dns.GetHostName() will be flagged by HP Fortify as a "Often Misused: Authentication" error.
