Thank you for providing new URLs. Unfortunately we were still able to reproduce the issue using Aspose.Cells 18.12.1. Upon calling sheet.Cells.DeleteBlankRows() we get the following exception:
System.ArgumentException: Destination array is not long enough to copy all the items in the collection. Check array index and length.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at System.BitConverter.ToInt32(Byte value, Int32 startIndex)
at .(Worksheet , Boolean , Int32 , Int32, Int32 , Int32 , Int32 , Int32 , Byte )
at ? .(Int32 , Int32 , Worksheet , Boolean)
at Aspose.Cells.RowCollection(Int32 , Int32 )
at Aspose.Cells.Cells.(Int32 , Int32 , DeleteOptions )
at Aspose.Cells.Cells.DeleteBlankRows(DeleteOptions options)
We’ve created a sample console app which allows to easily reproduce the issue, including the Excel file: https://we.tl/t-6BOqZzB7cF
Looking forward to your feedback. Please let us know if you need more info.
