How to call for Dispose in WinForms XlsIO?

ExcelEngine.Dispose() must be invoked after closing the workbook.

For example, if an Excel file is created/opened and saved after some manipulation, it has to be disposed. Please refer to the code example below to dispose of the ExcelEngine in our Winforms Xlso feature tour page.

C#

ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
IWorkbook workbook = application.Workbooks.Create(1);
// Do some manipulation
workbook.SaveAs(fileName);
workbook.Close();
excelEngine.Dispose();

VB

Dim excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
Dim workbook As IWorkbook = application.Workbooks.Create(1)
'Do some manipulation
workbook.SaveAs(fileName)
workbook.Close()
excelEngine.Dispose()
