使用打开的xml sdk 2.5将数据添加到现有的Excel中
我试图读取现有的Excel文件，并复制到另一个path，然后我试图插入数据到我克隆的文件。 但是我可以'插入数据。 我不知道我犯了什么错误。 但在这里，我已经给了我的代码。
错误发生在行sheetData.InsertAt<Row>(row,++rowIndex); 。 请帮我一下
Package spreadsheetPackage = Package.Open(destinationFile, FileMode.Open, FileAccess.ReadWrite); using (var document = SpreadsheetDocument.Open(spreadsheetPackage)) { foreach (System.Data.DataTable table in ds.Tables) { 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>(); //Sheet sheet = sheets.FirstOrDefault(); if(sheet==null) throw new Exception("No sheed found in the template file. Please add the sheet"); int rowIndex = 10, colIndex = 0; bool flag = false; var worksheetPart = (WorksheetPart)workbookPart.GetPartById(sheet.Id); var sharedStringPart = workbookPart.SharedStringTablePart; var values = sharedStringPart.SharedStringTable.Elements<SharedStringItem>().ToArray(); var rows = worksheetPart.Worksheet.Descendants<Row>(); List<String> columns = new List<string>(); foreach (System.Data.DataColumn column in table.Columns) { columns.Add(column.ColumnName); } foreach (System.Data.DataRow dsrow in table.Rows) { Row row = new Row(); foreach (String col in columns) { DocumentFormat.OpenXml.Spreadsheet.Cell cell = new Cell(); cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String; cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(dsrow[col].ToString()); row.AppendChild<Cell>(cell); } sheetData.InsertAt<Row>(row,++rowIndex); } }
在添加行之前，您应该提到实例的行索引…
row.RowIndex = (UInt32)rowIndex++;
