C# EPPlus OpenXML count rows

With a worksheet object called worksheet, worksheet.Dimension.Start.Row and worksheet.Dimension.End.Row should give you the information you need.

worksheet.Dimension.Address will give you a string containing the worksheet dimensions in the traditional Excel range format (e.g. 'A1:I5' for rows 1-5, columns 1-9).

There is a documentation file available. In many cases it might be just as quick to play around with the library and find the answer that way. EPPlus seems to be well designed - everything seems to be logically named, at least.

Thanks for that tip Quppa. I used it in my bid to populate a DataTable from a Workbook Spreadsheet as below:

    /// <summary>
    /// Converts a Worksheet to a DataTable
    /// </summary>
    /// <param name="worksheet"></param>
    /// <returns></returns>
    private static DataTable WorksheetToDataTable(ExcelWorksheet worksheet)
    {
        // Vars
        var dt = new DataTable();
        var rowCnt = worksheet.Dimension.End.Row;
        var colCnt = worksheet.Dimension.End.Column + 1;

        // Loop through Columns
        for (var c = 1; c < colCnt; c++ )
        {
            // Add Column
            dt.Columns.Add(new DataColumn());

            // Loop through Rows
            for(var r = 1; r < rowCnt; r++ )
            {
                // Add Row
                if (dt.Rows.Count < (rowCnt-1)) dt.Rows.Add(dt.NewRow());

                // Populate Row
                dt.Rows[r - 1][c - 1] = worksheet.Cells[r, c];
            }
        }

        // Return
        return dt;
    }

I am working with version 4.1 and it looks like they have added some properties (mentioned in comments from previous answers) to make this easier.

string Filepath = "c:\excelfile.xlsx";
FileInfo importFileInfo = new FileInfo(FilePath);
using(var excelPackage = new ExcelPackage(importFileInfo))
{
    ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1];
    int rowCount = worksheet.Dimension.Rows;
    int colCount = worksheet.Dimension.Columns;
}
