regular expression for credit card expiration date 1

[tperri]

I've found some sample regexs for dates, but they dont work in my validator. Does an yone have one they could share that will work with my asp.net reg expression validator?

Thanks in advance,
T

You can use a compare validator and set the compare type to date.

like jbenson says, the best would be a compare validotr for dates. why would u want to use a RegEx???

Known is handfull, Unknown is worldfull

The credit cards I have do not have a day. I do not believe the compare validator will work. Here is a regex that will take month year the year can be 2 or 4 digits. it only goes to the year 2019 and that may be too far out. Most of my credit cards are reissued every 3 years.
This will give you something to go on.

Match MyRegex = Regex.Match(_input,@"^(((0[5-9])|(1[0-2]))\/(06|2006)|((0[1-9])|(1[0-2]))\/(((0[7-9])|(1[0-9]))|((200[7-9])|(201[0-9]))))$",RegexOptions.IgnoreCase); 
if (MyRegex.Success) 
{
	Console.WriteLine(_input);
}
else
{
	Console.WriteLine(_input + " Is not month year or is less than 05/2006");
}

test results
Enter string: 04/06
04/06 Is not month year or is less than 05/2006
Enter string: 04/2006
04/2006 Is not month year or is less than 05/2006
Enter string: 01/07
