I have created a method which takes a workbook and saves it using the library method Save().
public Workbook Save(Workbook workbook)
{
workbook.Save(workbook.FileName, FileFormatType.Xlsx);
return workbook;
}
But while saving this throws a null pointer exception as follows:
NullReference Exception was unhandeled by user code.
"Object reference not set to an instance of an object."
This code works fine on 32-bit machines, but it breaks on 64-bit machines.
Also this works only with version 5.3.1.0, in 64-bit machines.
