Can a Custom C# object contain a property of the same type as itself?

Question

If I have created the following Employee object (simplified)...

 public class Employee
    {
        public Employee()
        {       
                


        

Answer 1

An object can indeed have a reference to an object of its own type.

This is how most Node type objects are implemented.

As for instantiation - you can pass in the Employee object to use as manager (passing in null for no manager). Constructors can have multiple overloads:

public Employee(Employee manager)
{
   this.Manager = manager;
}
