Answer 1

Exception from HRESULT: 0x800A03EC

Solution: Change the misValue to sheet1, sheet2 or sheet3.

xlWorkBook = xlApp.Workbooks.Add("sheet1"); 

This works for me. system.reflaction.missing.value what was that, it is not related to Excel.workbooks.add came from a Excel file default value. When you create a Excel file, the default worksheets are sheet1, sheet2 and sheet3.
