[英]MVC 5 How to upload Excel file and read rows till the last populated data row using EPPlus (OfficeOpenXml) ExcelPackage
[英]Using ExcelPackage to Read from Excel Template and Write to Excel
我正在使用以下代碼:
var assembly = Assembly.GetExecutingAssembly();
Stream streamToTemplete=assembly.GetManifestResourceStream("DailyAuction.xltx");
Stream streamToOutput = assembly.GetManifestResourceStream("dailyAuctionEmail.xls");
//using (ExcelPackage excelPackage = new ExcelPackage(newFile, templateFile))
using(streamToTemplete)
using (streamToOutput)
{
using (ExcelPackage excelPackage = new ExcelPackage(streamToOutput, streamToTemplete))
{
ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets["Daily Auction"];
int startRow = 4;
int row = startRow;
foreach (DailyEmail dailyEmail in listDailyEmail) //iterate through all the rows in the list
{
worksheet.Cells[row, 1].Value = dailyEmail.As_At.ToString("dd-MMM-yy HH:mm");
worksheet.Cells[row, 2].Value = dailyEmail.Auction_Date.ToString("dd-MMM-yy");
}
excelPackage.Save();
}
}
var attachment = new Attachment(streamToOutput, new ContentType("application/vnd.ms-excel"));
但是,我收到一條錯誤消息,說streamToTemplate和streamToOutput為null。 似乎是什么問題? 另外,其余代碼是否可以正常工作?
