Is it mandatory to call the "Dispose()"-method of an object that implements it or is the reserved memory be freed by the GC at a later time anyhow? If yes, why should I use IDisposable at all?

If I use GC.SuppressFinalize(this) like in the example, and forget to "manually" dispose a used managed component in the Dispose-method, do I then have a memory leak?

class MyClass : IDisposable
	private bool _isDisposed = false;

	~MyClass ()
	{
		Dispose( false );
	}

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

	protected virtual void Dispose( bool disposing )
	{
		if( !this._isDisposed )
		{
			// release unmanaged resources here

			if( disposing )
			{
				// release local managed resources here
			}
			this._isDisposed = true;
		}
	}
}

If Dispose() is not called, the Finalizer will do the cleanup.

the interface IDisposable should only be used, if the classes uses unmanaged resources
