c# – 如何确保我们只有一个实例,并以正确的方式处理它

从Disposable Singleton我可以看出意见是分歧的,单身是否可以是不可信的.也许两者都有更好的解决方案？欢迎任何帮助.
现在我有一个IDisposable单例,如下所示：

using System;
using System.Runtime.InteropServices;

namespace Philips.Research.Myotrace.DataReading.Devices
{
    class MyDevice: IDisposable
    {
        private static volatile MyDeviceInstance;
        private static object SyncRoot = new Object();

        private bool disposed = false;

        private MyDevice()
        {
            //initialize unmanaged resources here (call LoadLibrary,Initialize,Start etc)
        }

        public MyDevice GetInstance()
        {
            if (Instance == null)
            {
                lock (SyncRoot)
                {
                    if (Instance == null)
                    {
                        Instance = new MyDevice();
                    }
                }
            }

            return Instance;
        }

        public void Dispose()
        {
            this.Dispose(true);
        }

        protected virtual void Dispose(bool disposing)
        {
            if (!this.disposed)
            {
                if (disposing)
                {
                    //dispose of unmanaged resources here (call Stop and Close from reflection code

                    Instance = null;
                }

                this.disposed = true;
            }
        }

        [DllImport("devicedrivers.dll")]
        private static extern bool Initialize();
        [DllImport("devicedrivers.dll")]
        private static extern bool LoadLibrary();
        [DllImport("devicedrivers.dll")]
        private static extern bool Start();
        [DllImport("devicedrivers.dll")]
        private static extern bool Stop();
        [DllImport("devicedrivers.dll")]
        private static extern bool Close();
        //and few more
    }
}
