∟Getting Operating System Information

This section provides a tutorial example on how to use execution environment class, System.Environment, to retrieve information about the OS (Operating System).

To test some of properties and methods supported on the System.Environment class, I wrote this tutorial example:

// EnvironmentInfo.cs
// Copyright (c) 2008 HerongYang.com. All Rights Reserved.

using System;
class EnvironmentInfo {
   public static void Main() {
      String[] arguments = Environment.GetCommandLineArgs();
      Console.WriteLine("Command line arguments: {0}",
         String.Join(", ", arguments));

      Console.WriteLine("Machine name: {0}",
         Environment.MachineName);

      OperatingSystem os = Environment.OSVersion;
      Console.WriteLine("Operating system: {0}", os.ToString());

      Console.WriteLine("# of CPU: {0}", Environment.ProcessorCount);

      Console.WriteLine("Uptime: {0} seconds",
         Environment.TickCount/1000);

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

      Console.WriteLine("Current directory: {0}",
         Environment.CurrentDirectory);

      Console.WriteLine("Temporary directory: {0}",
         Environment.GetEnvironmentVariable("TEMP"));
   }
}

Running this example on my Windows 7 machine, I got:

Command line arguments: EnvironmentInfo
Machine name: USDED-000716
Operating system: Microsoft Windows NT 6.1.7601 Service Pack 1
# of CPU: 4
Uptime: 25871 seconds
Logical drives: C:\, D:\, E:\
Current directory: C:\herong
Temporary directory: C:\Users\herong\AppData\Local\Temp
