I am uploading records from Excel file to Database. My uploaded data contains Date value. I want to check whether the uploaded date is in dd.MM.yyyy format or not. How can i do this? I have tried DateTime.TryParse() and DateTime.TryParseExact() functions, but it returns false.
My code is :

DateTime date;

        if (dr["From_Date"].ToString() != "")
        {
            if (DateTime.TryParseExact(dr["From_Date"].ToString(), "dd.MM.yyyy", null, DateTimeStyles.None, out date))
            {
                return "Please specify \"From_Date\" in dd.mm.yyyy format.";
            }
        }
