尝试使用c对两列进行排序excel范围

Question

我在Excel中有一个范围，我需要按两列进行排序。数据总是从A列到AA列，我需要先按列A（这是一个日期列，最早到最新），然后按列F（数字列，从最小到最高）对它进行排序。行数会有所不同。

这是我到目前为止，请记住我相对较新的C＃。

  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JobDataSheet.Sort.Apply();线的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."

这对我来说是什么在起作用：

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); 
    }
