To which family do data types that store references to objects in memory belong?

Data types that store references to objects in memory belong to the family of reference types in C#. Unlike value types, which store data directly, reference types store the address of the object in managed heap.

Examples of reference types:

• Classes (class)
• Interfaces (interface)
• Delegates (delegate)
• Arrays (array)

Example:

class Person { public string Name; }

Person p = new Person(); // p is a reference to an object in memory
