MinValue & MaxValue attribute for properties

Question

Is it possible to make attribute which can limit minimum or maximum value of numbers.

Example:

[MinValue(1), MaxValue(50)]
public int Size { get; set         


        

Answer 1

Although it is possible to create a custom attribute, attributes are just metadata for the member they annotate, and cannot change its behavior.

So, you won't get the behavior you want with a plain attribute. You need something to process the attributes in order to enact the desired behavior.

Take a look at TypeConverters for a possibility.
