我有一个 C# 程序将结果输出到 Excel 电子表格。每行包含竞争对手的信息，包括几个字段，例如姓名、身份证号码、地址、分数等，每个字段位于不同的列中。我想根据分数对所有这些竞争对手进行排序（所以我想对这些行进行排序），记录从高到低降序排序。解决此问题的最佳方法是什么？这是我正在尝试但不起作用的代码。

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

啊哈，我刚刚做了，遗憾的是代码是在 VB.NET 中，如果你翻译成 C# 有任何困难，请告诉我

        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

这对我有用，但我必须添加一个带有 EPPLUS 的表才能使这条线工作：

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;

我不再添加表格，只是将带有 epplus 的自动过滤器设置为 sheet.AutoFilter 在较大的 Excel 文件中不为 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();

我将不再使用 Excel Interop 类。
已经有多种 API 可以很好地发挥作用。

另一个很棒的 SO 帖子是阅读文件。这可以为您指明使用非互操作 C# 类编写文件的正确方向。
