IDisposable模式,SafeFileHandle是非托管资源吗?

IDisposable 由Resharper生成的模式:

[NotNull]
private SafeFileHandle Handle { get; }

#region IDisposable

private bool IsDisposed { get; set; }

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

private void ReleaseUnmanagedResources()
{
    // TODO release unmanaged resources here
}

private void Dispose(bool disposing)
{
    if (IsDisposed)
        return;

    ReleaseUnmanagedResources();

    if (disposing)
        Handle.Dispose();

    IsDisposed = true;
}

~Whatever()
{
    Dispose(false);
}

雷斯哈珀认为 SafeFileHandle CreateFile ).

应该 安全文件句柄
