策略模式（strategy)行为型模式c#简单例子

例子主是运用策略模式分解几种移动算法。

namespace adapterpattern
{
    public partial class StrategyFrom : Form
    {
        public StrategyFrom()
        {
            InitializeComponent();
        }

            Context context1 = new Context(new LeftMove ());
            context1.moveMethod1();

            context1.moveMethod2();
            listBox1.Items.Add(moveData .moveString );
            Context context2= new Context(new RightMove());//算法变动后
            context2.moveMethod1();
            listBox1.Items.Add(moveData.moveString);
            context2.moveMethod2();
            listBox1.Items.Add(moveData.moveString);
           
        }
    }
    public interface IProessMove//表达算法抽象（strategy）
    {
        void Process();
    }
    public class Context
    {
        IProessMove proessMove;//对象组合
        public Context(IProessMove proessMove)//策略模式的连接点
        {
            this.proessMove = proessMove;
        }
