Open File Dialog, One Filter for Multiple Excel Extensions?
I want to use an OpenFileDialog object to browse to an excel file. I would like to set the filter to open files with different types of excel extensions like: .xls, .xlsm, .xlsx and so on.
what I am using is this:
OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files(.xls)|*.xls|
Excel Files(.xlsx)|*.xlsx| Excel Files(*.xlsm)|*.xlsm";
This works, but the user must select the correct excel file type from the dropdown in the OpenFileDialog.
Does anyone know if there a way to apply one filter for all types of Excel extensions?
Something like: "...Excel Files (.xls, .xlsx, .xlxm)|*.xls, *.xlsx, *.xlsm;"
Thanks in advance for any replies.
Use a semicolon
OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";
If you want to merge the filters (eg. CSV and Excel files), use this formula:
OpenFileDialog of = new OpenFileDialog();
of.Filter = "CSV files (*.csv)|*.csv|Excel Files|*.xls;*.xlsx";
Or if you want to see XML or PDF files in one time use this:
of.Filter = @" XML or PDF |*.xml;*.pdf";
