Is IDisposable.Dispose() called automatically? [duplicate]

Answer 1

To make sure the resources are correctly disposed, you need to both implement IDisposable and call Dispose in the destructor(finalizer).

class Foo : IDisposable
{
    private bool m_disposed = false;

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

    ~Foo()
    {
        Dispose(false);
    }

    protected void Dispose(bool disposing)
    {
        if (!m_disposed)
        {
            if (disposing)
            { 
                //release managed resources
            }
            //release unmanaged resources

            m_disposed = true;
        }
    }
}
