Hi, It''s been a late frustrating night. I have tried several ways to copy one workbook to another in memory (I have a baseline workbook, that has 15 sheets in it that I need to make several copies of to pump data into).

Is there a easy way to do this? like:
IWorkbook newWB = oldWB.CopyToNew()

I want to do this in memory to speed up my app vs. doing a disk based copy.....

I have tried cut/paste to clipboard - it crashes.
I have tried copying the sheets collection from one to the other with AddCopy() - it crashes.
Finally I wrote a loop and tried to use AddCopy() on each worksheet.. - it crashes..

Here is the code sinppet and exception... Please tell me what is wrong....

IWorkbook workbook = application.Workbooks.Create();
for (int i = 0; i < templateWorkbook.Worksheets.Count; i++ )

System.ArgumentOutOfRangeException was unhandled

Hi David,

I was not able to reproduce the problem. Here is the sample that I used for testing.

Please take a look at the sample above and let me know if you have any other questions. Would it be possible to provide me your sample xls file in which you are able to reproduce the issue? It will help me in investigating further on this issue.
