 static void Main(string[] args) { var spreadsheetDocument = SpreadsheetDocument.Create("F:\\OpenXml.xlsx", SpreadsheetDocumentType.Workbook); var workbookpart = spreadsheetDocument.AddWorkbookPart(); workbookpart.Workbook = new Workbook(); WorksheetPart worksheetPart = workbookpart.AddNewPart(); worksheetPart.Worksheet = new Worksheet(new SheetData()); Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild(new Sheets()); Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Sheet1" }; sheets.Append(sheet); var sheetData = worksheetPart.Worksheet.GetFirstChild(); for (int i = 0; i < 10; i++) { Row row = new Row(); for (int j = 0; j < 10; j++) { Cell dataCell = new Cell(); dataCell.CellValue = new CellValue($"{i + 1}行{j + 1}列"); dataCell.DataType = new EnumValue(CellValues.String); row.AppendChild(dataCell); } sheetData.Append(row); } workbookpart.Workbook.Save(); spreadsheetDocument.Close(); } 

 static void Main(string[] args) { using (SpreadsheetDocument doc = SpreadsheetDocument.Open(@"F:\OpenXml.xlsx", false)) { WorkbookPart wbPart = doc.WorkbookPart; Sheet mysheet = (Sheet)doc.WorkbookPart.Workbook.Sheets.ChildElements.FirstOrDefault(); Worksheet worksheet = ((WorksheetPart)wbPart.GetPartById(mysheet.Id)).Worksheet; SheetData sheetData = (SheetData)worksheet.ChildElements.FirstOrDefault(); foreach (var row in sheetData.ChildElements) { foreach (var cell in (row as Row).ChildElements) { var cellValue = (cell as Cell).CellValue; if (cellValue != null) { Console.WriteLine(cellValue.Text); } } } } }
