我正在使用tempalte excel表创建一个excel表。

我有一个代码

  try
    {
        FileInfo newFile = new FileInfo(@"D:\ExcelFromTemplate.xlsx");
        FileInfo template = new FileInfo(@"D:\template.xlsx");

        using (ExcelPackage xlPackage = new ExcelPackage(newFile,template))
        {

            ExcelWorksheet worksheet = xlPackage.Workbook.Worksheets["Sheet1"];

            ExcelCell cell = worksheet.Cell(5,1);
            cell.Value = "15";

            //worksheet.Cell(5, 1).Value = "Soap";

            //xlPackage.Save();
            Response.Write("Excel file created successfully");
        }

    }
    catch (Exception ex)
    {
        Response.WriteFile(ex.InnerException.ToString());
    }  

此代码创建与模板excel文件相同的新excel文件,但无法添加单元格值。为什么?

我曾尝试过两种方法,如上面的单元格代码(5,1)。但excel表创建时不会写入单元格值。我们如何添加它。

您需要保存文件以保留所做的更改。使用save()

  try
        {
            FileInfo newFile = new FileInfo(@"D:\ExcelFromTemplate.xlsx");
            FileInfo template = new FileInfo(@"C:\Example.xlsx");

            using (ExcelPackage xlPackage = new ExcelPackage(newFile , template))
            {

               //Added This part
               foreach (ExcelWorksheet aworksheet in xlPackage.Workbook.Worksheets)
                {
                    aworksheet.Cell(1, 1).Value = aworksheet.Cell(1, 1).Value;
                }

                ExcelWorksheet worksheet = xlPackage.Workbook.Worksheets["My Data"];

                ExcelCell cell = worksheet.Cell(5, 1);
                cell.Value = "15";

                //worksheet.Cell(5, 1).Value = "Soap";

                xlPackage.Save( );
                //Response.Write("Excel file created successfully");
            }

        }
        catch (Exception ex)
        {
            //Response.WriteFile(ex.InnerException.ToString());
        }

遇到了问题。这个问题是ExcelPackage固有的。 同样,您必须打开每个工作表并对其进行一些更改才能保存。
