How to get Date format and Date Order?

Dear Experts,

                    below code i can get the left,top,etc.. but i want to get Date Field format

ReportObject ReportObject = rpt.ReportDefinition.ReportObjects[i];

FieldObject  FieldObject = (FieldObject)ReportObject;

                     int Left = FieldObject.Left;

                    int top = FieldObject.Top;

                    string name = FieldObject.Name;

like i  wants to get Date Order (DMY,MDY,YMD)....

if i get this i generate to XML after that i inserted into DB.

once i inserted into DB, again i read from DB dynamically assigned to Report.

as like,

FieldObject.Left = dr("LEFT")

FieldObject.Top = dr("TOP")

is this possible to reassign the date format to Report?

please help to get this...

thanks in advance

Mani.
