【问题描述】：
我想要达到的效果如下图所示：
我遇到的结果和问题如下图所示：
这是我的代码生成的结果文件，应该有预期的内容。
单击“是”按钮后的窗口提示。
我的运行代码如下：
主要方法：
public static void Main(string[] args)
{
WriteExcelService writeExcelService = new WriteExcelService();
Dictionary<string, List<string>> contentList = new Dictionary<string, List<string>>
{
{ "en-US",new List<string> (new string[] { "Dummy text 01","Dummy text 02"}) },
{ "es-ES",new List<string> (new string[] { "Texto ficticio 01", "Texto ficticio 02"}) }
};
string inputFile = @"C:\{username}\Desktop\Valentines_Day.xlsx";
string sheetName = "Copy";
writeExcelService.WriteValueToCell(inputFile, sheetName, contentList);
}
WriteValueToCell 方法：
char columnName = 'I';
uint rowNumber = 1;
foreach (var keys in contentList.Keys)
{
foreach (var value in contentList.Where(v => v.Key == keys).SelectMany(v => v.Value))
{
string cellAddress = String.Concat(columnName, rowNumber);
this.Write(filepath, sheetName, value, cellAddress, rowNumber);
int tempColumn = (int)columnName;
columnName = (char)++tempColumn;
}
columnName = 'I';
++rowNumber;
}
写法：
private void Write(string filepath, string sheetName, string value, string cellAddress,uint rowNumber)
{
// Create a spreadsheet document by supplying the filepath.
// By default, AutoSave = true, Editable = true, and Type = xlsx.
using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook))
{
//writeExcelService.WriteValueToCell(outputFilePath, sheetName, cellAddress, value.Value);
// 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 = sheetName };
sheets.Append(sheet);
// Get the sheetData cell table.
SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
// Add a row to the cell table.
Row row;
row = new Row() { RowIndex = rowNumber };
sheetData.Append(row);
// In the new row, find the column location to insert a cell.
Cell refCell = null;
foreach (Cell cell in row.Elements<Cell>())
{
if (string.Compare(cell.CellReference.Value, cellAddress, true) > 0)
{
refCell = cell;
break;
}
}
// Add the cell to the cell table.
Cell newCell = new Cell() { CellReference = cellAddress };
row.InsertBefore(newCell, refCell);
// Set the cell value to be a numeric value.
newCell.CellValue = new CellValue(value);
newCell.DataType = new EnumValue<CellValues>(CellValues.Number);
}
}
我的问题是：
我的代码执行，但是一旦打开结果文件，它会提示我上面发布的窗口，并且文件是空的。如果我调试代码以逐个插入内容列表，它可以正确写入单元格@ 987654330@ 或J2。由于我的代码为每个列表内容创建SpreadsheetDocument，因此我在下面的代码中更改了SpreadsheetDocument的创建方法：
using (SpreadsheetDocument spreadsheetDocument = File.Exists(filePath) ?
SpreadsheetDocument.Open(filepath, true) :
SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook))
{
}
但我遇到了异常
此父级只允许该类型的一个实例。
有人可以帮我解决这个问题吗？
提前欣赏。

您想插入文本对吗？那为什么你的代码中有这一行：
newCell.DataType = new EnumValue<CellValues>(CellValues.Number);? -
@FortyTwo 我的代码有误。我修改了算法并将行号作为参数传递，而不是硬编码。
