Question

I have two classes: Role and CustomRole

public class CustomRole
{
    public string RoleName { get; set; }
    public int RoleId { get; set; }
}

public class Role
{
    public string RoleName { get; set; }
    public int RoleId { get; set; }
    public int MyRole { get; set; }
}

at compile time I have a delegate like this:

Func<CustomRole, bool> Del = o => o.RoleId > 0;

The problem is at runtime I need to create one more delegate with same condition but table name is changed

Func<Role, bool> Del1 = o => o.RoleId > 0;

How can I achieve this?

Answer 1

You could have both Role and CustomRole implement a IRole interface that includes the RuleId property, then make your delegate use IRole.

If that is not an option, you could look into duck typing.
