Can Model Classes contain Methods, and Constructor

Question

Q: `Can Model Classes contain Methods, and Constructor ?" [BEST PRACTICE]

I have an employee Model class which consists of the Employee's name, age, salary etc...

public class Employee
{
    public string Name { get; set; }
    public int Age { get; set; }
    public int Salary { get; set; }
}

so can the above Model Class contain some self updating methods [like updating the employee's age every 1 hour with a timer or something] and\or constructors or it is better to handle all that things from the executer ?

Answer 1

Why couldn't they? The real answer is: it depends on your use case. Patterns, such as something being a model class, are recommendations, common ways of doing things, not unbreakable dogmas.

Note: The example “updating the employee's age every 1 hour with a timer or something” is fundamentally wrong. Storing age is fundamentally wrong, unless you are storing a snapshop to some moment in time. A much better solution would be to store date of birth, and compute the age. For example, by defining an Age property with a getter only.

Answer 2

A model should contain all logic related to the model (this is DSL) so, yes it can update itself each hour. and when u define auto properties, it's same as defining setters and getter, so of course you can add methods, and constructors as well.
