OpenXML how to get cell in range

问题

Please help me to get cell in range (ex from A:1 to E:11 are all cells in rectangular). For now, my ideal is

 Worksheet worksheet = GetWorksheet(document, sheetName);
        SheetData sheetData = worksheet.GetFirstChild<SheetData>();
        IEnumerable<Cell> cells = sheetData.Descendants<Cell>().Where(c =>
            c.CellReference >= A:1 &&
            c.CellReference <= E:11 &&
            );
        int t = cells.Count();

But this code does not work. Thanks

It won't be that easy to compare cell's CellReference with a string. And yes, what you are currently doing is wrong. You simply cannot compare strings for Higher or Lower in such a way.

You have two options.

Option 1 :

You can take cell reference and break it down. That means separate characters and numbers and then give them values individually and compare

A1 - > A and 1 -> Give A =1 so you have 1 and 1

E11 -> E and 11 -> Give E = 5 so you have 5 and 11

So you will need to breakdown the CellReference and check the validity for your requirement.

Option 2 :

If you notice above it's simply we take a 2D matrix index (ex : 1,1 and 5,11 which are COLUMN,ROW format). You can simply use this feature in comparison. But catch is you cannot use LINQ for this, you need to iterate through rows and columns. I tried to give following example code, try it

 using (SpreadsheetDocument myDoc = SpreadsheetDocument.Open("PATH", true))
    {
        //Get workbookpart
        WorkbookPart workbookPart = myDoc.WorkbookPart;

        // Extract the workbook part
        var stringtable = workbookPart.GetPartsOfType<SharedStringTablePart>().FirstOrDefault();

        //then access to the worksheet part
        IEnumerable<WorksheetPart> worksheetPart = workbookPart.WorksheetParts;

        foreach (WorksheetPart WSP in worksheetPart)
        {
            //find sheet data
            IEnumerable<SheetData> sheetData = WSP.Worksheet.Elements<SheetData>();

            int RowCount = 0;
            int CellCount = 0;

            // This is A1
            int RowMin = 1;
            int ColMin = 1;

            //This is E11              
            int RowMax = 11;
            int ColMax = 5;

            foreach (SheetData SD in sheetData)
            {
                foreach (Row row in SD.Elements<Row>())
                {
                    RowCount++; // We are in a new row

                    // For each cell we need to identify type
                    foreach (Cell cell in row.Elements<Cell>())
                    {
                        // We are in a new Cell
                        CellCount++;

                        if ((RowCount >= RowMin && CellCount >= ColMin) && (RowCount <= RowMax && CellCount <= ColMax))
                        {

                            if (cell.DataType == null && cell.CellValue != null)
                            {
                                // Check for pure numbers
                                Console.WriteLine(cell.CellValue.Text);
                            }
                            else if (cell.DataType.Value == CellValues.Boolean)
                            {
                                // Booleans
                                Console.WriteLine(cell.CellValue.Text);
                            }
                            else if (cell.CellValue != null)
                            {
                                // A shared string
                                if (stringtable != null)
                                {
                                    // Cell value holds the shared string location
                                    Console.WriteLine(stringtable.SharedStringTable.ElementAt(int.Parse(cell.CellValue.Text)).InnerText);
                                }
                            }
                            else
                            {
                                Console.WriteLine("A broken book");
                            }

                        }
                    }
                    // Reset Cell count
                    CellCount = 0;
                }
            }
        }
    }

This actually work. I tested.
