使用Environment 來擷取系統的資訊

Environment 類可檢索資訊，如命令列參數、結束代碼、環境變數設定、呼叫堆疊的內容、上次系統引導以來的時間，以及公用語言運行庫的版本

    Console.WriteLine("命令列: {0}", Environment.CommandLine);

    String[] arguments = Environment.GetCommandLineArgs();
    Console.WriteLine("命令列參數的字串數組: {0}", String.Join(", ", arguments));

    Console.WriteLine("目前的目錄: {0}", Environment.CurrentDirectory);
    Console.WriteLine("機器名: {0}", Environment.MachineName);

    Console.WriteLine("系統分行符號: {0}  第1行{0}  第2行{0}  第3行",
                          Environment.NewLine);

    Console.WriteLine("平台標識符和版本號碼: {0}", Environment.OSVersion.ToString());

    Console.WriteLine("系統目錄: {0}", Environment.SystemDirectory);

Console.WriteLine("毫秒數: {0}", Environment.TickCount);
    Console.WriteLine("域: {0}", Environment.UserDomainName);

    Console.WriteLine("互動模式: {0}", Environment.UserInteractive);
    Console.WriteLine("使用者名稱: {0}", Environment.UserName);

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

    Console.WriteLine("臨時目錄{0}.",
                           Environment.GetEnvironmentVariable("TEMP")); //臨時目錄

    Console.WriteLine("得到系統內容變數: ");
    IDictionary    environmentVariables = Environment.GetEnvironmentVariables();
    foreach (DictionaryEntry de in environmentVariables)
        {
        Console.WriteLine("  {0} = {1}", de.Key, de.Value);
        }

    Console.WriteLine("系統目錄: {0}",
                 Environment.GetFolderPath(Environment.SpecialFolder.System));

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