Hi Experts,

i try to sort an excelsheet based on a column polulated with date entries.

The problem seems to be, that the dates are handled as text.

What i want:
01.01.2013
02.01.2013
..
01.02.2013
02.02.2013

What i get:
01.01.2013
01.02.2013
..
02.01.2013
02.02.2013

The column (to be precise: The cells in the range to sort) is formated as a "Date" field in the worksheet.

Here is the Code i use:
Excel.Range range = oSheet.get_Range("A4:W" + iLastUsedRow, Type.Missing);

range.Sort(range.Columns[1, Type.Missing], Excel.XlSortOrder.xlAscending,Excel.XlYesNoGuess.xlNo,Type.Missing,Type.Missing,Excel.XlSortOrientation.xlSortColumns,Excel.XlSortMethod.xlPinYin,Excel.XlSortDataOption.xlSortTextAsNumbers);
 
System.Runtime.InteropServices.Marshal.ReleaseComObject(range);

Open in new window


Any help is greatly appreciated!

Now that i have written down the problem, i instantly see a possible answer:

This may have to do with localization?

Here in europe the date is generally of a "DD.MM.YYYY" format.

Since my routine changes globalization to "en-US" (otherwise the file wont open) maybe excel treats the date in a "MM.DD.YYYY" format and therefore the current result is "correct"?

UPDATE:
I have done a little testing and found out that the localization indeed was the problem.

When i chance it to "de-DE" (German) before sorting, it works like i need it.

Might not be the sexiest solution out there, but fits me needs.
