C# Excel 范围排序

Question

I would like to sort a range. The first row (Row 3 in the Excel workbook) contains the column headers, which need sorted, left to right, in ascending order:

Excel.Range tempRange = ws.get_Range("F3", "H8");

tempRange.Sort(Type.Missing,
                    Excel.XlSortOrder.xlAscending,
                    Type.Missing,
                    Excel.XlSortOrder.xlAscending,
                    Excel.XlSortOrder.xlAscending,
                    Type.Missing,
                    Excel.XlSortOrder.xlAscending,
                    Excel.XlYesNoGuess.xlYes,
                    Type.Missing,
                    Type.Missing,
                    Excel.XlSortOrientation.xlSortColumns,
                    Excel.XlSortMethod.xlPinYin,
                    Excel.XlSortDataOption.xlSortNormal,
                    Excel.XlSortDataOption.xlSortNormal,
                    Excel.XlSortDataOption.xlSortNormal);

This currently generates the error 'Sort method of Range class failed'.

I've tried various parameters at the start of the sort method, but this generates the '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 the same or blank' error message.

Where am I going wrong?

The equivalent VBA Works fine:

 With ActiveWorkbook.Worksheets("Sheet1").Sort
    .SetRange Range("F3:H8")
    .Header = xlYes
    .MatchCase = False
    .Orientation = xlLeftToRight
    .SortMethod = xlPinYin
    .Apply
End With

Thanks very much

I stated the Range as the first parameter & set the Orientation to Excel.XlSortOrientation.xlSortRows.

                tempRange.Sort(tempRange,
                    Excel.XlSortOrder.xlAscending,
                    Type.Missing, Type.Missing,
                    Excel.XlSortOrder.xlAscending,
                    Type.Missing,
                    Excel.XlSortOrder.xlAscending,
                    Excel.XlYesNoGuess.xlYes, 
                    Type.Missing,
                    Type.Missing,
                    Excel.XlSortOrientation.xlSortRows,
                    Excel.XlSortMethod.xlPinYin,
                    Excel.XlSortDataOption.xlSortNormal,
                    Excel.XlSortDataOption.xlSortNormal,
                    Excel.XlSortDataOption.xlSortNormal);
