I'm trying to copy a worksheet form a workbook to another.

Code: Select all
Workbook w1 = new workbook();
Workbook w2 = new workbook();


Here i got the ApplicationException "Cannot find required constructor". With an older version of Spire.XLS this worked without problems, where there any changes?

I've updated to the newest Version (VisualStudio shows 'Runtimeversion v2.0.50727).

The problem still remains. I'm not able to add a copy of a worksheet to another. I tried different parameter combinations for AddCopy(). Each shows the earlier mentioned exception.

BTW: what shows the enum WorksheetCopyType? I couldn't find any clue in the demos or the help file.
