如何在c#中的List <string>类型的公共属性中添加值？

using System;
using System.Collections.Generic;

public class MyClass
{
    public List<string> MyList { get; set; }

    public MyClass()
    {
        MyList = new List<string>();
    }

    public void AddItem(string item)
    {
        MyList.Add(item);
    }
}

public class Program
{
    public static void Main()
    {
        MyClass myClass = new MyClass();
        myClass.AddItem("Hello");
        myClass.AddItem("World");

        foreach (string item in myClass.MyList)
        {
            Console.WriteLine(item);
        }
    }
}
