make Attribute, which describes AccessLevel of model property?

Question

So... I have this simple model called Employee:

public class Employee {

    public int WorkerID { get; set; }

    public string FirstName { get; set; }

    public string LastName { get; set; }

    public int Salary { get; set; }
}

And I want to "decorate" all properties with AccessLevel like this:

[AccessLevel(1)]
public class Employee {
    [AccessLevel(1)]
    public int WorkerID { get; set; }

    [AccessLevel(1)]
    public string FirstName { get; set; }

    [AccessLevel(1)]
    public string LastName { get; set; }

    [AccessLevel(2)]
    public int Salary { get; set; }
}

I've read about Attributes, but still don't know how to create right one and somehow access it like

 Employee.Salary.GetAccessLevel();

How can I make that kind of Attribute? Or maybe there is a better way to do this?

You can try to use reflection get property attribute by GetCustomAttribute method and use linq to check the auth value.

typeof(Employee)
        .GetTypeInfo()
        .GetProperties()
        .Where(x=>x.GetCustomAttribute<AccessLevel>().val > 1) // here can write your logic.
        .Select(x => x.Name);
