ExcelPackage和98,000行

Question

我想用codeplex excelpackage写一个excel文件(2007),但是要花很多时间编写excel文件.我没有找到任何可以接受数据源的方法.

我的代码片段:

var newFile = new FileInfo(GlobalVariables.Compare2007Path);

using (var excelpackage = new ExcelPackage(newFile))
{
  var myWorkbook = excelpackage.Workbook;
  myWorkbook.Worksheets.Add("sheetname");

  var xlWorkSheet = xlWorkBook.Worksheets["sheetname"];

  //loop the data and fill the columns
  var rowCount = 2;
  foreach (var compare in objCompare)
  {
    xlWorkSheet.Cell(rowCount, 1).Value = compare.adserverIdSite.ToString();
    xlWorkSheet.Cell(rowCount, 2).Value = compare.site;
    xlWorkSheet.Cell(rowCount, 3).Value = compare.adserverIdZone.ToString();
    xlWorkSheet.Cell(rowCount, 4).Value = compare.zone;
    xlWorkSheet.Cell(rowCount, 5).Value = compare.position;
    xlWorkSheet.Cell(rowCount, 6).Value = compare.weekday;
    xlWorkSheet.Cell(rowCount, 7).Value = compare.oldimps.ToString();
    xlWorkSheet.Cell(rowCount, 8).Value = compare.olduu.ToString();
    xlWorkSheet.Cell(rowCount, 9).Value = compare.oldimpsuu.ToString();
    xlWorkSheet.Cell(rowCount, 10).Value = compare.newimps.ToString();
    xlWorkSheet.Cell(rowCount, 11).Value = compare.newuu.ToString();
    xlWorkSheet.Cell(rowCount, 12).Value = compare.newimpsuu.ToString();
    xlWorkSheet.Cell(rowCount, 13).Value = compare.diffimps.ToString();
    xlWorkSheet.Cell(rowCount, 14).Value = compare.diffimpsperc.ToString();
    rowCount++;
  }
  excelpackage.Save();
}

或者除了excelpackage还有其他选择.

我找到了我的excel包性能解决方案.这是您需要在excelPackage上应用的补丁.补丁可以在这里找到.查找id:1042或更新1233(该补丁中的更多功能).

使用该补丁,您可以在空白工作表上添加数据表.添加98000条记录和14列只需几秒钟.
