The "Environment" class of the System namespace is handy for getting and setting various operating system related information. The "Environment" class to retrieve information such as the current directory, network details, machine name, OS versions, environment variable settings, contents of the call stack, time since last system boot, and the version of the common language runtime.

There is a lot of information that can be extracted with the "Environment" class. Below is a small code snippet that might help you get started.

public static void GetEnvironmentDetails()
        {
            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);
            //  <-- Keep this information secure! -->
            Console.WriteLine("MachineName: {0}", Environment.MachineName);
            Console.WriteLine("OSVersion: {0}", Environment.OSVersion);
            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);
            Console.WriteLine("GetFolderPath: {0}",
                         Environment.GetFolderPath(Environment.SpecialFolder.System));

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