集合类中嵌套定义和引用的举例

        在开发应用程序时，有时候需要定义简单的类，有时候需要定义复杂的集合类型，复杂的集合类型既可以用于存储简单类的对象，也可以用于存储其它集合类型。这时候就用到了集合类中嵌套定义和引用。下面代码示例。

ListBase类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ListEmbeddedTest
{
    public class ListBase
    {
        //int number;
        public MyList parentList;

    }
}

MyList类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.Collections;

namespace ListEmbeddedTest
{
    public class MyList : ListBase
    {
        public ArrayList m_children = new ArrayList();
    }
}

World类： 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ListEmbeddedTest
{
    public class World : ListBase
    {
        public double  radius;
        public string name;

    }
}

PathPoint类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ListEmbeddedTest
{
    public class PathPoint : ListBase
    {
        public int pointCount;
    }
}

PathList类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ListEmbeddedTest
{
    public class PathList : MyList
    {
        public int totalNum;
    }
}

Consumer类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ListEmbeddedTest
{
    //消费者：使用项目中定义的所有类
    public class Consumer
    {
        public string consumerName;
        public MyList renderableObjectsList=new MyList();
    }
}

Program类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ListEmbeddedTest
{
    class Program
    {
        static void Main(string[] args)
        {
            PathPoint pathPoint=new PathPoint();
            pathPoint.pointCount=4;

            PathPoint pathPoint1 = new PathPoint();
            pathPoint1.pointCount = 3;

            PathList pathList = new PathList();
            pathList.totalNum = 7;
            pathList.m_children.Add(pathPoint);
            pathList.m_children.Add(pathPoint1);

            pathPoint.parentList = pathList;
            pathPoint1.parentList = pathList;

            World world = new World();
            world.radius = 6378137;
            world.name = "Earth";

            Consumer consumer = new Consumer();
            consumer.consumerName = "主应用程序";
            consumer.renderableObjectsList.m_children.Add(pathList);
            consumer.renderableObjectsList.m_children.Add(world);

            System.Console.WriteLine("Hello");
        }
    }
}

详细的解析就不多说了，大家运行源码体会吧。
