A lot derived classes without functonality only to "know" their type

I think there is a better solution for the following problem.

Let's say we have the following structure of classes:

class Foo
{
    public int Id { get; set; }
}

class Bar1 : Foo
{

}

class Bar2 : Foo
{

}

class Bar3 : Foo
{

}
//.. A lot more of these Foo derivations

The derived classes has no functionality. The following examples give an idea what the classes are for:

• Access a specific object from a specific type (object from type Bar3 with Id 5) in a list of Foo objects.


• Displaying different data in a GUI related to a specific object from type Foo.

Is there a better way to identify one of these objects without derivating them?

Thanks!
