昨天下午我把《C#仿魔兽世界密保卡简单实现》 中的代码用面向对象的方法重构了一遍，引入了2个类：MatrixCard和Cell。MatrixCard描述的是密保卡，构造函数中会随机生成一个二 维矩阵，所以每次new一个MatrixCard对象，就已经生成了一张密保卡。Cell是单元格的意思，将行号、列号、列名做了封装。 MatrixCard类中保留了之前的大部分静态方法，以便灵活调用。
由于本人水平有限，这次的设计并不是非常完美，并且也有一些遗憾。比如现在只能通过Cell[i]的方式来访问单元格，而不可以像Cell["A0"]这样写。有空的时候哥去研究一下重载索引器，争取把它实现。下面发代码：
MatrixCard类：
