Understanding COM Proxy Management

NetOffice manages COM proxies for you to avoid any kind of memory leaks and it makes sure the instance of the Excel.Application object is cleaned up. This shutdowns the Excel.exe process.

public void Tutorial01Main()
    // start application
    Excel.Application application = new Excel.Application();
    application.DisplayAlerts = false;

    Excel.Workbook book = application.Workbooks.Add();

    * now we have 2 new COM Proxies created.
    * the first proxy was created while accessing the Workbooks collection from
    * application the second proxy was created by the Add() method from Workbooks
    * and stored now in book with the application object we have 3 created proxies
    * now. the workbooks proxy was created about application and the book proxy was
    * created about the workbooks.
    * NetOffice holds the proxies now in a list as follows:
    * Application
    *   + Workbooks
    *     + Workbook
    * any object in NetOffice implements the IDisposible Interface.
    * use the Dispose() method to release an object. The method releases all created
    * child proxies too.

    // close Excel and release application instance and any child objects
    // (workbooks in this case)
