ASPOSE：如何正确获取工作表中的总行数

Question

Currently using Aspose for .NET in a C# WebService. I am currently having issues getting the correct Total Rows using worksheet.Cells.Rows.Count It is showing that I have around 230 rows but inside the file, I only have 14 rows. I am guessing because I reuse my Excel file and deleted some rows by highlighting the rows then pressing the delete key.

When I recreate a brand new Excel file, then copy-paste the 14 values in the new file. The worksheet.Cells.Rows.Count works correctly.

Would this be a bug in the library or am I deleting the values in Excel file wrongly or I am using a wrong count property?

Am I missing something?

TIA

Answer 1

Well, RowCollection/ColumnCollection.Count attribute would give you total number of rows/columns which are initialized, so it won't be always reliable to get total number of data rows/cols. I think you should use Worksheet.Cells.MaxDataRow and Worksheet.Cells.MaxDataColumn properties to get the farthest (last) row/column indices (0 - based), see the sample code segment for your reference: eg Sample code:

    Workbook workbook = new Workbook("Book1.xlsx");
     //Get the farthest (last) row's index (zero-based) which contains data.
     int lastRowIndex = workbook.Worksheets[0].Cells().MaxDataRow;

     //Get the farthest (last) column's index (zero-based) which contains data.
     int lastColIndex = workbook.Worksheets[0].Cells.MaxDataColumn;
......

Hope, this helps a bit.

I used this but get wrong column count:

var dataTable = worksheet.Cells.ExportDataTable(0, 0,worksheet.Cells.Rows.Count, worksheet.Cells.Columns.Count, options);

Instead of worksheet.Cells.Rows.Count and worksheet.Cells.Rows.Count use these: worksheet.Cells.MaxRow + 1 and worksheet.Cells.MaxColumn + 1

This works correctly:

var dataTable = worksheet.Cells.ExportDataTable(0, 0, worksheet.Cells.MaxRow + 1, worksheet.Cells.MaxColumn + 1, options);
