class A
{
    public Thread thread
    { get; set; }
}

我应该实现IDisposable并将Thread属性设置为null吗？

class A : IDisposable
{
    public Thread Thread
    { get; set; }

    protected bool Disposed
    { get; set; }


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

    protected virtual void Dispose(bool disposing)
    {
        if (!this.Disposed)
        {
            if (disposing)
            {
                if (Thread != null)
                    Thread = null;
            }

            Disposed = true;
        }
    }
}

或不？
为什么？
