Commented Unassigned: creating multiple files at once [9328]

hi,

I have an issue when creating multiple excel files. The problem is that every single file who is opened, opens is the same instance of excel (i.e. opened 3 excel files, 1 excel.exe in task manager). its unhandy when working with multiple generated reports.
I tried to create diferent workbooks,that didnt helped, and also noticed that file size sums up, and last generated file size is the biggest, independently on the content of file. It seems that some information remains the same for all generated files(did i forgot something important to clean?).
So is there any way to create separate multiple excel files?

here is my example:

var wb = new XLWorkbook();
var wb2 = new XLWorkbook();
string select = "select * from table";

//firstfile
sheetName = "name1";
sheetName2 = "name2";
DataTable dataTable = DB.selectfromDBSA(select, sheetName);
wb.AddWorksheet(dataTable);
dataTable = DB.selectfromDBSA(select, sheetName2);
wb.AddWorksheet(dataTable);
wb.SaveAs("temp/test.xlsx");
dataTable.Clear();
wb.Worksheets.Delete(sheetName);
wb.Worksheets.Delete(sheetName2);
//for example this file weight is 175kb


//second file

sheetName = "name1";
sheetName2 = "name2";
DataTable dataTable = DB.selectfromDBSA(select, sheetName);
wb2.AddWorksheet(dataTable);
dataTable = DB.selectfromDBSA(select, sheetName2);
wb2.AddWorksheet(dataTable);
wb2.SaveAs("temp/test.xlsx");
dataTable.Clear();
wb2.Worksheets.Delete(sheetName);
wb2.Worksheets.Delete(sheetName2);
//for example this file weight is 285kb, but information is the same, because its same query to database.

thanks,
Comments: also forgot to mention, if there is diffrent query to secont file, ant the result has less collumns that the first one, thiese columns remains in the second file, even if its a second workbook, and all sheets were deleted from the first file.
