Question

Say I have a list of objects called components:

List<object> components = new List<object>();

Say it’s populated with objects of the classes engine, wheel, frame. Now, I want to make a function that takes a class as a parameter and returns true if the list has an object of that class. Like this:

public static bool HasComponent( *the class* ) { 
    foreach(object c in components) {
        if(c is *the class*)
           return true;
    }

    return false;
} 

How do i go about doing that? is it possible?

Answer 1

Use generics:

public static bool HasComponent<T>() { 
    foreach(object c in components) {
        if(c is T)
           return true;
    }

    return false;
}

Call it:

Obj.HasComponent<Wheel>();
