Release Unmanaged Resources of the Workbook

Aspose.Cells provides Workbook.Dispose() method to release the unmanaged resources of the Workbook object. The dispose pattern is used only for objects that access unmanaged resources, such as file and pipe handles, registry handles, wait handles or pointers to blocks of unmanaged memory. This is because the garbage collector is very efficient at reclaiming unused managed objects, but it is unable to reclaim unmanaged objects.

Workbook object now implements the System.IDisposable interface which has a single method Dispose(). You can either directly call the Workbook.Dispose() method or you can use the Using statement to call this method automatically.
