Question

我使用open xml sdk导出excel。我得到excel文件并将该文件复制到另一个地方，然后我插入带有数据的新行。

我应该使用open xml sdk将这些行设为只读（或者我要锁定）..

怎么做？

Answer 1

我引用了以下链接Excel File Password Protection with Open XML SDK。

在这里，我给了你完整的代码，从目录中打开文件并插入单元格。这里我只插入了一个单元格。您可以根据需要插入。在这里，我插入了锁定的单元格。找到这个，它对你很有帮助..

注意：这里我提到的代码只是读取现有文件并插入行和单元格并锁定已手动插入的单元格

谢谢。

// To read the xlsx file..
    Package spreadsheetPackage = Package.Open(destinationFile, FileMode.Open, FileAccess.ReadWrite);

// create a document
                    using (var document = SpreadsheetDocument.Open(spreadsheetPackage))
                    {

                        var workbookPart = document.WorkbookPart;
                        //var workbook = workbookPart.Workbook;

                        var sheet = workbookPart.Workbook.Descendants<Sheet>().FirstOrDefault();
                        Worksheet ws = ((WorksheetPart)(workbookPart.GetPartById(sheet.Id))).Worksheet;
                        SheetData sheetData = ws.GetFirstChild<SheetData>();

                        if (sheet == null || sheetData == null)
                            throw new Exception("No sheet found in the template file");

                        int rowIndex;

                        var worksheetPart = (WorksheetPart)workbookPart.GetPartById(sheet.Id);
                        var rows = worksheetPart.Worksheet.Descendants<Row>();
                        DocumentFormat.OpenXml.Spreadsheet.Cell cell = new Cell();

// Getting row index from the web config..
                        if (!int.TryParse(WebConfigurationManager.AppSettings["BasReportRowIndex"].ToString(), out rowIndex))
                            throw new Exception("Mention template row index in the configuration file");

                        // Create Cell format .. It's necessary to lock the cell
                        CellFormat lockFormat = new CellFormat() { ApplyProtection = true, Protection = new Protection() { Locked = true } };
                        WorkbookStylesPart sp = workbookPart.GetPartsOfType<WorkbookStylesPart>().FirstOrDefault();

                        if (sp == null)
                            sp = worksheetPart.AddNewPart<WorkbookStylesPart>();

                        sp.Stylesheet.CellFormats.AppendChild<CellFormat>(lockFormat);
                        sp.Stylesheet.CellFormats.Count = UInt32Value.FromUInt32((uint)sp.Stylesheet.CellFormats.ChildElements.Count);
                        sp.Stylesheet.Save();

                        foreach (WeekSummary summary in report.Summary)

                            // Before insert Row we've to mention the index where the row must be inserted
                            row.RowIndex = (UInt32)rowIndex++;

                            row.AppendChild<Cell>(new Cell() { DataType = CellValues.String, CellValue = new CellValue(summary.name ?? ""), StyleIndex = 0 });

                            // Append the row to sheet data.. 
                            sheetData.AppendChild<Row>(row);
                        }
// Till the line It's only to create and insert row..

                        // Now we've to mention the sheet protection. It's necessary for the whole sheet. Then only cells will be locked
                        SheetProtection sheetProtection = new SheetProtection();

                        // these are the "default" Excel settings when you do a normal protect

                        // After the following lines, the cell will be locked...
                        bool bFound = false;
                        OpenXmlElement oxe = worksheetPart.Worksheet.FirstChild;
                        foreach (var child in worksheetPart.Worksheet.ChildElements)
                        {
                            // start with SheetData because it's a required child element
                            if (child is SheetData || child is SheetCalculationProperties)
                            {
                                oxe = child;
                                bFound = true;
