我在excel中有一个范围，我需要按两列排序。数据的范围总是从 A 列到 AA 列，我需要首先按 A 列（这是一个日期列，所以从最旧到最新）对其进行排序，然后按 F 列（数字列，从最小到最高）进行排序。行数会有所不同。

这是我到目前为止所得到的，请记住我对 c# 比较陌生。

         Excel.Worksheet JobDataSheet = new Excel.Worksheet();

         foreach (Excel.Worksheet tmpSheet in Globals.ThisAddIn.Application.ActiveWorkbook.Sheets)
         {
             if (tmpSheet.Name == "Job Labour" || tmpSheet.Name == "Job Materials" || tmpSheet.Name == "Job Cost Report")
             {
                 tmpSheet.Delete();
             }
             if (tmpSheet.Name == "Job Cost")
                 JobDataSheet = tmpSheet;
         }


         int MyCount = JobDataSheet.UsedRange.Rows.Count;

          //Sort Collection by Date & Ref Line
         Excel.Range tempRange = JobDataSheet.get_Range("A2:A" + MyCount);
         Excel.Range tempRange2 = JobDataSheet.get_Range("F2:F" + MyCount);

         JobDataSheet.Sort.SortFields.Clear();
         JobDataSheet.Sort.SortFields.Add(tempRange // First Key
                                           ,Excel.XlSortOn.xlSortOnValues
                                           ,Excel.XlSortOrder.xlAscending
                                           ,Type.Missing
                                           ,Excel.XlSortDataOption.xlSortNormal);
         JobDataSheet.Sort.SortFields.Add(tempRange2 // Second Key
                                           , Excel.XlSortOn.xlSortOnValues
                                           , Excel.XlSortOrder.xlAscending
                                           , Type.Missing
                                           , Excel.XlSortDataOption.xlSortNormal);

         JobDataSheet.Sort.SetRange(JobDataSheet.get_Range("A1:AA" + MyCount));
         JobDataSheet.Sort.Header = Excel.XlYesNoGuess.xlYes;
         JobDataSheet.Sort.MatchCase = false;
         JobDataSheet.Sort.Orientation = Excel.XlSortOrientation.xlSortRows;
         JobDataSheet.Sort.SortMethod = Excel.XlSortMethod.xlPinYin;
         JobDataSheet.Sort.Apply();

在行JobDataSheet.Sort.Apply();excel 抛出"The sort reference is not valid. Make sure that it's within the data you want to sort, and the first Sort By box isn't in the same or blank."

这对我有用：

private void SortExcel()
{
    //Set up
    Excel.Application oXL;
    Excel._Workbook oWB;
    Excel._Worksheet oSheet;
    Excel.Range oRng;
    Excel.Range oLastAACell;
    Excel.Range oFirstACell;

    //Start Excel and get Application object.
    oXL = new Excel.Application();
    oXL.Visible = true;

    //Get a new workbook.;
    oWB = (Excel._Workbook)(oXL.Workbooks.Open(@"C:\Book.Xlsx"));

    //Get Sheet Object
    oSheet = (Excel.Worksheet)oWB.Worksheets["Sheet1"];

    //Get complete last Row in Sheet (Not last used just last)     
    int intRows = oSheet.Rows.Count;

    //Get the last cell in Column AA
    oLastAACell = (Excel.Range)oSheet.Cells[intRows, 27];

    //Move courser up to the last cell in AA that is not blank
    oLastAACell = oLastAACell.End[Excel.XlDirection.xlUp];

    //Get First Cell of Data (A2)
    oFirstACell = (Excel.Range)oSheet.Cells[2, 1];

    //Get Entire Range of Data
    oRng = (Excel.Range)oSheet.Range[oFirstACell, oLastAACell];

    //Sort the range based on First Columns And 6th (in this case A and F)
    oRng.Sort(oRng.Columns[1, Type.Missing],Excel.XlSortOrder.xlAscending, // the first sort key Column 1 for Range
              oRng.Columns[6, Type.Missing],Type.Missing, Excel.XlSortOrder.xlAscending,// second sort key Column 6 of the range
              Type.Missing, Excel.XlSortOrder.xlAscending,  // third sort key nothing, but it wants one
              Excel.XlYesNoGuess.xlGuess, Type.Missing, Type.Missing, 
              Excel.XlSortOrientation.xlSortColumns, Excel.XlSortMethod.xlPinYin,   
              Excel.XlSortDataOption.xlSortNormal,
              Excel.XlSortDataOption.xlSortNormal, 
              Excel.XlSortDataOption.xlSortNormal);
    }
