Detecting on the property names Count or Length does complicate the design a bit. MaxLengthAttribute and MinLengthAttribute Output of the application looks like this. The advantage of using the Data Annotation validators is that they enable you to perform validation simply by adding one or more attributes such as the Required or StringLength attribute to a class property.
