Get the current Workbook Object in C#

问题

I've been writing an application in C# which creates Custom Document properties in an Excel spreadsheet, I have a function for this which takes in a Workbook Object...

However, actually getting the current Workbook object is proving to be quite annoying, I am using ExcelDNA to add functionality, however, I can't seem to pass my function a valid Workbook COM object.

This is the way I am currently doing it it seems to work really well

 using Excel = Microsoft.Office.Interop.Excel;

Then you get active workbook

        //Gets Excel and gets Activeworkbook and worksheet
        Excel.Application oXL;
        Excel.Workbook oWB;
        Excel.Worksheet oSheet;
        oXL = (Excel.Application)Marshal.GetActiveObject("Excel.Application"); 
        oXL.Visible = true;
        oWB = (Excel.Workbook)oXL.ActiveWorkbook; 

        docProps = oWB.CustomDocumentProperties

Then I would try what you have and see how it works

Hope this helps

If you need to find the activeworkbook with C#, if you are using Office Interop, you can try this kind of code:

(Workbook)Globals.ThisAddIn.Application.ActiveWorkbook;

As @Govert explained above in his comment:

using Excel = Microsoft.Office.Interop.Excel;
using ExcelDna.Integration;

// Get the correct application instance
Excel.Application xlapp = (Excel.Application)ExcelDnaUtil.Application;

// Get active workbook
Excel.Workbook wbook = xlapp.ActiveWorkbook;

GetActiveObject() looks in the Running Object Table (ROT) and gives you the last Excel instance opened which may not corresponding with top Z order excel window.

Loop through the Z order and find the matching workbook.
