Hello Ben Reitman!
Below I give you some line of code which is provide an example of Environment Class in C#: -

using System;
using System.Collections;

class Sample
{
    public static void Main()
    {
        String str;
        String nl = Environment.NewLine;

        //
        Console.WriteLine();
        Console.WriteLine("-- Environment members --");

        // Invoke this sample with an arbitrary set of command line arguments.
        Console.WriteLine("CommandLine: {0}", Environment.CommandLine);

        String[] arguments = Environment.GetCommandLineArgs();
        Console.WriteLine("GetCommandLineArgs: {0}", String.Join(", ", arguments));


        // <-- Keep this information secure! -->
        Console.WriteLine("CurrentDirectory: {0}", Environment.CurrentDirectory);
        Console.WriteLine("ExitCode: {0}", Environment.ExitCode);

        Console.WriteLine("HasShutdownStarted: {0}", Environment.HasShutdownStarted);

        // <-- Keep this information secure! -->
        Console.WriteLine("MachineName: {0}", Environment.MachineName);

        Console.WriteLine("NewLine: {0} first line{0} second line{0} third line",
                              Environment.NewLine);

        Console.WriteLine("OSVersion: {0}", Environment.OSVersion.ToString());
        Console.WriteLine("StackTrace: '{0}'", Environment.StackTrace);


        // <-- Keep this information secure! -->
        Console.WriteLine("SystemDirectory: {0}", Environment.SystemDirectory);
        Console.WriteLine("TickCount: {0}", Environment.TickCount);


        // <-- Keep this information secure! -->
        Console.WriteLine("UserDomainName: {0}", Environment.UserDomainName);
        Console.WriteLine("UserInteractive: {0}", Environment.UserInteractive);

        // <-- Keep this information secure! -->
        Console.WriteLine("UserName: {0}", Environment.UserName);

        Console.WriteLine("Version: {0}", Environment.Version.ToString());
        Console.WriteLine("WorkingSet: {0}", Environment.WorkingSet);


        // No example for Exit(exitCode) because doing so would terminate this example.
        // <-- Keep this information secure! -->

        String query = "My system drive is %SystemDrive% and my system root is %SystemRoot%";
        str = Environment.ExpandEnvironmentVariables(query);
        Console.WriteLine("ExpandEnvironmentVariables: {0} {1}", nl, str);
        Console.WriteLine("GetEnvironmentVariable: {0} My temporary directory is {1}.", nl,
                               Environment.GetEnvironmentVariable("TEMP"));

        Console.WriteLine("GetEnvironmentVariables: ");
        IDictionary environmentVariables = Environment.GetEnvironmentVariables();
        foreach (DictionaryEntry de in environmentVariables)
        {
            Console.WriteLine(" {0} = {1}", de.Key, de.Value);
        }

        Console.WriteLine("GetFolderPath: {0}",
                     Environment.GetFolderPath(Environment.SpecialFolder.System));
        String[] drives = Environment.GetLogicalDrives();

        Console.WriteLine("GetLogicalDrives: {0}", String.Join(", ", drives));
        Console.ReadKey();

    }

}
