What is cause of LockShareViolation Exception in older versions in WinForms Excel?
Older version:
In our older version, if the file is already opened, we get an exception "Syncfusion.XlsIO.Implementation.Exceptions.LockShareViolationException." You can catch the exception by using:
Syncfusion.XlsIO.Implementation.Exceptions.LockShareViolationException class
In version v6.3.0.30:
"In our latest version", .NET Excel library, we use file streams to read and write files, and hence "IOException" is thrown with the message "The process cannot access the file 'fileName.xls' because it is being used by another process." There is no specific exception in our library to handle this. You can also open the file as read-only when the file is already opened by using the OpenReadOnly method as shown below:
C#
IWorkbook workbook = application.Workbooks.OpenReadOnly(filename);
VB
Dim workbook As IWorkbook = application.Workbooks.OpenReadOnly(filename);
Take a moment to peruse the documentation where you can find basic Excel document processing options along with the features like import and export data, chart, formulas, conditional formatting, data validation, tables, pivot tables and protect the Excel documents, and most importantly, the PDF, CSV and Image conversions with code examples.
