# .Net. I need the answer ASAP

The following project should be completed as a c#.net website. It should consist of one form, dateconvert.aspx, and one code behind file, dateconvert.aspx.cs. Create a program that accepts a dd/mm/yyyy or dd-mm-yyyy input string representing a gregorian calendar date and converts it to its plain text equivalent. The program should be able to generate at least the error messages listed below. Your answer may not use any date or datetime library. (hint: years that are evenly divisible by 100 are leap years unless they are also evenly divisible by 400. February has 29 days in a leap year and 28 days otherwise.) examples: input output 12/06/1981 december 6, 1981 01/12/1966 january 12, 1966 02/29/1999 error: invalid number of days 13/12/2008 error: month must be between 1 and 12, inclusive 4/4/1999 error: input must be in dd/mm/yyyy or ddmm- yyyy format days per month month days january 31 february 28 or 29 march 31 april 30 may 31 june 30 july 31 august 31 september 30 october 31 november 30 december 31

Hey friend , purely i dont understand your problem ,, still i m giving solution please revert back me if i am incorrect.
At the input text box where you taking the datetime please implement the validation (whatever you want ) and when user click on submit button first verify the conditions and if the true then nothing user can process and if false then accept the input
