How to create a List of object into a user defined class

Question

My first class :

 

public class Person

{

public string name{get; set;}

public int Id{get; set;}

 

public list<Company> companies {get; set;} 

 

}

I want to list of companies the person been.  

 

Company Class:

 

public class Company

{

public string name{get; set;}

public string address{get; set; }

} 

 

In Controller I am assigning the list:

List<Person> personList = new List<Person>();

 

I am returning this personlist to the view.

 

How can I create list of user defined type within a user defined class and  How can I show A person multiple companies?
