使用Excel Interop C＃sortingExcel行

我有一个C＃程序，将结果放在Excel电子表格中。 每行包含竞争对手的信息，包括姓名，身份证号码，地址，分数等几个字段，每个字段在不同的列中。 我想根据分数sorting所有这些竞争对手（所以我想对这些行进行sorting），logging从最高到最低sorting。 什么是最好的方式去做这件事？ 这是我正在尝试哪些不工作的代码。

Excel.Range sortRange; sortRange = worksheet.get_Range("A14", "K32"); Excel.Range scoreColumn; scoreColumn = worksheet.get_Range("C14", "C32"); sortRange.Sort(scoreColumn, Excel.XlSortOrder.xlDescending,

我会放弃使用Excel Interop类。
已经有多个API可以完成很好的工作。

无需Interop创buildExcel

另一个伟大的SO职位是阅读文件。 这可能会指向使用非interop C＃类编写文件的正确方向。

啊哈，我刚刚做了这个，不幸的是代码是在VB.NET中，让我知道如果你有任何困难转化为C＃

  Dim lastrow As Integer = 0 lastrow = xlsSheet.UsedRange.Row + xlsSheet.UsedRange.Rows.Count - 1 Dim myRange = xlsSheet.range("A2", "Q" & lastrow) myRange.Select() xlsApp.ActiveWorkbook.Worksheets("your_work_sheet_name").Sort.SortFields.Add(Key:= _ xlsSheet.Range("A2:A" & lastrow), Order:=Microsoft.Office.Interop.Excel.XlSortOrder.xlAscending) xlsApp.ActiveWorkbook.Worksheets("your_work_sheet_name").Sort.SortFields.Add(Key:= _ xlsSheet.Range("B2:B" & lastrow), Order:=Microsoft.Office.Interop.Excel.XlSortOrder.xlAscending) With xlsApp.ActiveWorkbook.Worksheets("your_work_sheet_name").Sort .SetRange(myRange) .Header = Microsoft.Office.Interop.Excel.XlYesNoGuess.xlYes .MatchCase = False .Orientation = Microsoft.Office.Interop.Excel.XlSortOrientation.xlSortColumns .SortMethod = Microsoft.Office.Interop.Excel.XlSortMethod.xlPinYin .Apply() End With

这工作对我来说，但我不得不添加EPPLUS这一行的工作表：

 sheet.AutoFilter.Sort.SortFields.Add(oRange, XlSortOrder.xlAscending);</s> <s> // add the excel table entity with EPPLUS (available on Nuget) var table = ws.Tables.Add(range, "table1"); table.TableStyle = OfficeOpenXml.Table.TableStyles.Light2; 

我不再添加一个表，只是设置autofilter与epplus sheet.AutoFilter不是在较大的Excel文件为NULL

  var colindexM = ws.Cells["M5"].Start.Column; var endcell = ws.Cells[ws.Dimension.End.Row, ws.Dimension.End.Column]; var range = ws.Cells[4, 2, endcell.Start.Row, endcell.Start.Column]; range.AutoFilter = true; 

然后：

  //open workbook workBook = oXL.Workbooks.Open(outputfilepath, 0, false, 5, "", "", false, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false); //oXL.Visible = false; Worksheet sheet = workBook.Sheets["Rapport1"]; // set Date Format to the sort column Range rg = sheet.Cells[5, colindexM]; rg.EntireColumn.NumberFormat = "DD/MM/YYYY"; sheet.EnableAutoFilter = true; sheet.AutoFilter.Sort.SortFields.Add(rg, XlSortOn.xlSortOnValues, XlSortOrder.xlAscending,"", XlSortDataOption.xlSortTextAsNumbers ); sheet.AutoFilter.ApplyFilter(); workBook.Save(); oXL.Quit();
