I am currently working on a project where i need check whether a date that is inputted is valid.

i know how to use this using repetitive if functions.

for example;

to check the month you do

if (month <1 || month >12)

Then to check the day which is my problem. Each month has a different amount of days in it. i can see how to do an if loop which then has an inner loop.

i.e

if (month == 1)
{
if (day <1 || day > 31)
Application.Exit
}

then i would go on and do that for all twelve months changing the if function where necessary. but is there a way to do this with arrays?

Have you considered that you are reinventing the wheel?
Perhaps there is a function of the datetime variety that will do all this for you..

Try with DateTme.TryParse method .let me know it is working for u.

ok that apears to be working. Thankyou

My final problem. How would i go about outputting the date that i have just validated. like this.

i put in 22/03/09 originally then the program works out whether the day needs a nd, st, rd or th at the end of it and then outputs like this;

22nd March, 2009

I was trying to get you to look at the datetime functions for yourself to find the things like tryparse..

Perhaps you will now try and do a search on date time formats.

i put in 22/03/09 originally then the program works out whether the day needs a nd, st, rd or th at the end of it and then outputs like this;

i did not get this words..can u explain indetails so that i can help u...

ok I have now got the date inputted by the user in this format 12/12/1990 and have used the tryparse method to check for validity,



I now need to output that date as 12th December, 1990


i.e

Date:
Console.WriteLine("please insert a date")
date = Convert.ToString(Console.ReadLine())

String[] dateStrings = {date};
DateTime dateValue;


foreach (string dateString in dateStrings)
{
if (DateTime.TryParse(dateString, out dateValue))
goto output;
else
Console.WriteLine("\r\n {0}", date);
Console.WriteLine("\r\nError)


goto Date
}

I now want to output the date so that is outputs in a form like this 12th december 1990 instead of outputting as 12/12/09

Check out this:

Flush goto's...

Why do you do this? This is not C. Predeclaration makes code less readable.

Hi Foxipj,
and u can play with this Tostring method as well for different formats.
