Rather than posting the code "as is" as a text file on my server, I decided to create (and share) a little Visual Studio solution for it that hosts the source for the attributes in VB.NET and in C#. The Visual Studio solution that you can download at the end of this article contains two class libraries with attributes: one in VB.NET and one in C#. Feel free to download the code and make any modifications you see fit.
The original source was in VB only, but I used Telerik's great on-line source converter to quickly create C# versions of the attributes, except for one. I didn't have the time to fix the many compile errors in the ValidCreditCardNumberAttribute class, so it's not included in the C# version. The current solution includes the following attributes:
|Attribute name||Description||VB||C#||Contributed by|
|ExactLengthAttribute||Validates the exact length of a string.||Yes||Yes||Scott Brady|
|MaxLengthAttribute||Validates the maximum length of a string.||Yes||Yes||Scott Brady|
|MinLengthAttribute||Validates the minimum length of a string.||Yes||Yes||Scott Brady|
|RegularExpressionAttribute||Validates a string using a regular expression.||Yes||Yes||Scott Brady|
|ValidCreditCardNumberAttribute||Validates a credit card number.||Yes||No||Scott Brady|
If you feel like contributing to this little project, or have comments, remarks, bug fixes or questions about the ones that are currently available, please send me a message. Also, if you have a working C# version of the ValidCreditCardNumberAttribute class and you're willing to share it, you can send me the code,
My idea is to keep an up-to-date list of the attributes here, combined with the full source code for them. Once I receive new contributions, I'll add them to the download and update this article
Where to Next?

When you post a comment, you have to provide your name and the comment. Your e-mail address is optional and you only need to provide it if you want me to contact you. It will not be displayed along with your comment. I got sick and tired of the comment spam I was receiving, so I have protected this page with a simple calculation exercise. This means that if you want to leave a comment, you'll need to complete the calculation before you hit the Post Comment button.
If you want to object to a comment made by another visitor, be sure to contact me and I'll look into it ASAP. Don't forget to mention the page link, or the Doc ID of the document.
Please correct the following errors:
Unfortunately, something went wrong and your message or comments have not been submitted successfully.
There's a fair chance things broke down because you tried to post something that looks like HTML. Things that look like HTML include (X)HTML, obviously, XML, ASP.NET markup and c# generics syntax as all of them use the < and > characters.
If that's the case, try altering your message and remove anything that looks like an angled bracket. You can replace them with [ and ] for example so you can still make it look like HTML to some extend.
If, on the other hand, you were trying to spam this web site, I am pretty glad I caught you in the act and stopped you from doing so ;-)
Also, please don't use links in your posts; I had to block them to filter out most of the junk mail I am receiving.
The number you entered is not correct. Please enter the sum of the two numbers again.
