如何在我的另一个.NET应用程序中使用VSTO项目DLL for excel

Question

I have created a project using Visual studio 2010 office template(for excel 2007).and its working fine. I am performing my calculation in ThisWorkbook_Startup() method which is being using in Startup event, defined as

    #region VSTO Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InternalStartup()
    {
        this.Startup += new System.EventHandler(ThisWorkbook_Startup);
        this.Shutdown += new System.EventHandler(ThisWorkbook_Shutdown);

    }

    #endregion  

and I am using Global.Sheet1,Global.Sheet2 and Global.Sheet3 to write data in excel template and passing to my custom method as WriteExcel(Globals.Sheet1,Globals.Sheet2,Globals.Sheet3);

I want to use this dll in my another .net project, while I am doing so its initializing Globals.Sheet1,Globals.Sheet2,Globals.Sheet3 properties with null which is not expected. How can I get command on the Global properties to open and write data with defined template.

You need to use the Excel object model methods and properties instead. There is no Global class outside VSTO add-ins (belongs to the VSTO runtime only).

It looks like you need to automate Excel from another application. See How to automate Microsoft Excel from Microsoft Visual C#.NET for more information.

For example, you may find the Worksheets property in the Workbook and Applications classes.
