设计模式之面向对象基础(二)
t.Shout());

return "我的名字叫" + name + " " + result;
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
private Animal[] arrayAnimal;//动物数组
//动物报名
private void button3_Click(object sender, EventArgs e)
{
arrayAnimal = new Animal[2];
arrayAnimal[0] = new Cat("小花");
arrayAnimal [1]=new Dog ("丹丹")
}
private void button4_Click(object sender, EventArgs e)
{
foreach (Animal item in arrayAnimal )//遍历数组，让猫狗都Shout()
{
MessageBox.Show(item.Shout());
}
}
}
}
对这三大特性的理解还有待实践提高，希望大家给予指导！
