C# 2.0 中关于泛型的用法实例

1. 定义泛型类

using system;
using system.collections;
using system.collections.generic;
using system.text;

namespace windowsapplication1
{
    class blist<t>
    {
        arraylist arr = new arraylist();

        public t this[int i]
        {
            get
            {
                return (t)arr[i];
            }
            set
            {
               arr.add(value);
            }
        }

        public void add(t p_obj)
        {
            arr.add(p_obj);
        }

        public int count
        {
            get
            {
                return arr.count;
            }
        }

    }
}

2. 调用（放到任意的窗体事件中）
 private void button2_click(object sender, eventargs e)
        {

            blist<int> _list = new blist<int>(); // <int>里面可以替换任意已知类型
            for (int i = 0; i < 10; i++)
            {
                _list.add( i);
            }

            for (int i = 0; i < _list.count; i++)

                messagebox.show(_list[i].tostring());
        }
