Hi,friends
I encountered a problem. When I used the read range activity which belongs to excel to read an excel file, it prompted me that Excel could not open the file “~ $ Name.xlsx” because the file format or file extension was invalid. Make sure the file is not corrupted and that the file extension matches the format of the file.
But if use the activity which belongs to the workbook,it will be ok.
And the excel file path is used the method (system.io.directory.getfiles(“my directory path”)) to get.
