Please post the code that you have written and describe how it does not perform as you expect.... ASAP.

It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.

check this link , it will help you to get many ideas :
system.datetime.date
and you can use this codes in c# too .:

C#

DateTime dt = DateTime.Parse("02/22/2012");//you can put a textbox.text instead this date
if (dt.ToString("mm/dd/yyyy") == dt.GetDateTimeFormats()[3])// an if statement check if format is mm/dd/yyyy
    MessageBox.Show(dt.ToString());
else
    MessageBox.Show(dt.ToString("Invalid Date. Only number and forward slash (/) characters are allowed. The valid format is MM/DD/YYYY."));
