在c＃中使用openxml sdk来创buildxlsx文件

我使用OpenXml SDK创buildExcel文件时遇到了一些问题，我按照这里的说明操作。

class Program { static void Main(string[] args) { List<Person> persons = new List<Person>() { new Person() {FirstName="Brecht", LastName="Baekelandt", Age=29}, new Person() {FirstName="Pieter", LastName="Baekelandt", Age=28}, new Person() {FirstName="Leonie", LastName="Baekelandt", Age=21} }; string directory = Path.Combine(@"C:\Temp", "TestFiles"); string fileName = Path.Combine(directory, string.Format("TestFile{0:yyyy-MM-dd HH.mm.ss}.xlsx", DateTime.Now)); // Create a spreadsheet document by supplying the filepath. // By default, AutoSave = true, Editable = true, and Type = xlsx. using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument. Create(fileName, SpreadsheetDocumentType.Workbook)) { // Add a WorkbookPart to the document. WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart(); workbookpart.Workbook = new Workbook(); // Add a WorksheetPart to the WorkbookPart. WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>(); worksheetPart.Worksheet = new Worksheet(new SheetData()); // Add Sheets to the Workbook. Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook. AppendChild<Sheets>(new Sheets()); // Append a new worksheet and associate it with the workbook. Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart. GetIdOfPart(worksheetPart), SheetId = 1, Name = "mySheet" }; sheets.Append(sheet); SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>(); UInt32 rowIndex = 0; foreach (var person in persons) { var row = new Row() { RowIndex = rowIndex }; var firstNameCell = new Cell() { CellReference = "A" + (rowIndex + 1) }; firstNameCell.CellValue = new CellValue(person.FirstName); firstNameCell.DataType = CellValues.String; row.AppendChild(firstNameCell); Cell lastNameCell = new Cell() { CellReference = "B" + (rowIndex + 1) }; lastNameCell.CellValue = new CellValue(person.LastName); lastNameCell.DataType = new EnumValue<CellValues>(CellValues.String); row.AppendChild(lastNameCell); Cell ageCell = new Cell() { CellReference = "C" + (rowIndex + 1) }; ageCell.CellValue = new CellValue(person.Age.ToString()); ageCell.DataType = new EnumValue<CellValues>(CellValues.Number); row.AppendChild(ageCell); sheetData.AppendChild(row); rowIndex++; } workbookpart.Workbook.Save(); } } } 

这将创build以下的XML文件：

 <?xml version="1.0" encoding="utf-8"?> <x:worksheet xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main"> <x:sheetData> <x:row r="0"> <x:cr="A1" t="str"> <x:v>Brecht</x:v> </x:c> <x:cr="B1" t="str"> <x:v>Baekelandt</x:v> </x:c> <x:cr="C1" t="n"> <x:v>29</x:v> </x:c> </x:row> <x:row r="1"> <x:cr="A2" t="str"> <x:v>Pieter</x:v> </x:c> <x:cr="B2" t="str"> <x:v>Baekelandt</x:v> </x:c> <x:cr="C2" t="n"> <x:v>28</x:v> </x:c> </x:row> <x:row r="2"> <x:cr="A3" t="str"> <x:v>Leonie</x:v> </x:c> <x:cr="B3" t="str"> <x:v>Baekelandt</x:v> </x:c> <x:cr="C3" t="n"> <x:v>21</x:v> </x:c> </x:row> </x:sheetData> </x:worksheet> 

这应该没问题，但是当我打开xlsx文件时出现以下错误：

Excel在[文件]中发现不可读的内容。 你想恢复这个工作簿的内容？

当我单击是时，只有第一个人被添加到工作表。

我在这里做错了什么？

Answer 1

你的问题是与索引。 行索引从index 1开始

stream动应该工作。

  UInt32 rowIndex = 1; foreach (var person in persons) { var row = new Row() { RowIndex = rowIndex }; var firstNameCell = new Cell() { CellReference = "A" +rowIndex }; firstNameCell.CellValue = new CellValue(person.FirstName); firstNameCell.DataType = CellValues.String; row.Append(firstNameCell); Cell lastNameCell = new Cell() { CellReference = "B"+rowIndex }; lastNameCell.CellValue = new CellValue(person.LastName); lastNameCell.DataType = new EnumValue<CellValues>(CellValues.String); row.Append(lastNameCell); Cell ageCell = new Cell() { CellReference = "C"+rowIndex }; ageCell.CellValue = new CellValue(person.Age.ToString()); ageCell.DataType = new EnumValue<CellValues>(CellValues.Number); row.Append(ageCell); sheetData.Append(row); rowIndex++; }
