DateTime _effective_date = Convert.ToDateTime(Text         


        

Answer 1

This is a sample to compare datetime. you can change according to your requirement

 DateTime dtFromDate = DateTime.ParseExact(TextBoxFromDate.Text, "dd/MM/yyyy",
                                                   CultureInfo.InvariantCulture);
 DateTime dtToDate = DateTime.ParseExact(TextBoxToDate.Text, "dd/MM/yyyy",
                                                   CultureInfo.InvariantCulture);
 TimeSpan difference = dtFromDate - dtToDate;
 double days = difference.TotalDays;

 if (days > 0)
 {
   DivFormError.InnerText = "“From Date” cannot be greater than “To Date”";
 }
