如何获取和设置列表类属性?

Question

我是否在Main中设置并获得类型类程序属性的列表?如果我这样做，我会得到一个异常?

public class Person 
{
public List<Person> Children { get; set; }
public string Names { get; set; }
}
static void Main(string[] args) 
{
var person = new Person 
{
Names = "King"
};

person.Children.Add(new Person()); // Null Reference Exception
}

Answer 1

试试这个:

var person = new Person{Names= "King" , Children=new List<Person>()};
person.Children.Add(new Person())
