page 1 of 8
Published: 13 Apr 2007
Abstract
Enterprise Library 3 contains the ability to validate a business object and this validation occurs through a standard range of validators. The Framework also provides the ability to create custom validators, which is where this article will continue on to discuss the additional features of the Validation Block.

Introduction

Previously, I wrote about Enterprise Library 3 validation in ASP.NET pages, using the existing Validator classes defined in the Microsoft.Practices.EnterpriseLibrary.Validation namespace.  Through inheritance, it is easy to create your own custom validation and we will look at a few examples of this and see how you can create your own in your applications.

Validator doesn't inherit from that class, correct. You have to create an accompying attribute that works along side of it. Create another class that inherits from ValidatorAttribute (the attribute class). It has a method you need to override that uses your validator to validate the data. Sorry, I didn't include it in the article.

Base class Validator don't inherit System.Attribute. How can i use it in this way:
[StringLengthValidator(7, RangeBoundaryType.Inclusive, 150,
RangeBoundaryType.Inclusive,
"The email address must be between 7 and 150 characters",
Ruleset = "primary")
, ContainsCharactersValidator("@.", ContainsCharacters.All,
"The email must have an @ and at least one period",
Ruleset = "primary"),
EmailDomainValidator(".com", ".net", ".edu", ".gov", ".biz", ".tv",
Ruleset =
"primary")]
????
