Информация о системе в .Net

Этот пост скорее просто памятка .Net программистам о том, как получать некоторые важные свойства системы - версию Runtime, 64 или 32-битная система, сколько используется процессоров и пр. Все эти проверки можно найти в интернете или копанием в классах вроде System.Environment, но лично мне удобно держать все в одном вспомогательном классе.

Класс целиком из ядра RunServer:

/// <summary>
/// System information class
/// </summary>
public static class SystemInfo
{
    /// <summary>
    /// Is there Mono Runtime available?
    /// </summary>
    public static readonly bool IsMono =
                        Type.GetType("Mono.Runtime") != null;

    /// <summary>
    /// Are we on x86 architecture?
    /// </summary>
    public static readonly bool IsX86 = IntPtr.Size == 4;

    /// <summary>
    /// Are we on x64 architecture?
    /// </summary>
    public static readonly bool IsX64 = IntPtr.Size == 8;

    /// <summary>
    /// Are we using Server Garbage Collector?
    /// </summary>
    public static readonly bool IsServerGC = GCSettings.IsServerGC;

    /// <summary>
    /// Is there console windows attached or we are running in
    /// service/GUI app?
    /// </summary>
    public static readonly bool IsConsole =
                        Console.OpenStandardOutput() != Stream.Null;

    /// <summary>
    /// Assembly was compiled in Debug mode?
    /// </summary>
    public static readonly bool IsDebug =
#if DEBUG
                        true;
#else
                        false;
#endif

    /// <summary>
    /// Runtime version
    /// </summary>
    public static readonly Version RuntimeVersion =
                        Environment.Version;

    /// <summary>
    /// Operating System version
    /// </summary>
    public static readonly Version OSVersion =
                        Environment.OSVersion.Version;

    /// <summary>
    /// CPU count
    /// </summary>
    public static readonly int ProcessorCount =
                        Environment.ProcessorCount;

    /// <summary>
    /// Dumps system information the specified stream.
    /// </summary>
    /// <param name="stream">Output stream</param>
    public static void Dump(StreamWriter stream)
    {
        stream.WriteLine("Is Mono: {0}", IsMono);
        stream.WriteLine("Is x86: {0}", IsX86);
        stream.WriteLine("Is x64: {0}", IsX64);
        stream.WriteLine("Is ServerGC: {0}", IsServerGC);
        stream.WriteLine("Is Console: {0}", IsConsole);
        stream.WriteLine("Is Debug: {0}", IsDebug);
        stream.WriteLine("Runtime Version: {0}", RuntimeVersion);
        stream.WriteLine("OS Version: {0}", OSVersion);
        stream.WriteLine("CPU Count: {0}", ProcessorCount);
    }
}
