Environment in C#

What the process knows about where it is running.

Console.WriteLine(Environment.MachineName);
Console.WriteLine(Environment.ProcessorCount);
Console.WriteLine(Environment.CurrentDirectory);

// environment variables, with a shrug for the missing ones
var home = Environment.GetEnvironmentVariable("HOME") ?? "(not set)";
Console.WriteLine(home);

var profile = Environment.GetFolderPath(
    Environment.SpecialFolder.UserProfile);
Console.WriteLine(profile);

How it works

1. MachineName, ProcessorCount and the current directory, direct.
2. GetEnvironmentVariable returns null; ?? supplies the shrug.
3. GetFolderPath resolves well-known folders portably.
