@MaTya You cannot add attributes at runtime to already existent type. Maybe you will benefit from approach similar to Fluent Validation project (http://fluentvalidation.codeplex.com/). If you need dynamically determine input validation rules you can take for example a Builder pattern and combined with Fluent Validation you can achieve the goal. Anyways providing more background will help people here to help you find an answer. – Alexander Manekovskiy Feb 03 '14 at 05:35
