C# Reflection - Get Custom Scripts on GameObject

I would like to get all of the custom scripts attached to a GameObject without knowing their types prior to retrieving them. Is this even possible?

All component that are attached to a GameObject must inherits from UnityEngine.Component.
Therefore a simple code like this one can retrieve them all:

Component[] components = gameObject.GetComponents(typeof(Component));

If your are looking for scripts only, then MonoBehaviour is the base class:

MonoBehaviour[] scripts = gameObject.GetComponents(typeof(MonoBehaviour));

After that, you can get the type with:

Debug.Log(components*.GetType()); // this use C# reflection*

or:
Debug.Log(scripts*.GetType()); // this use C# reflection*
