C#中使用GDI+与PrintDocument实现打印
近日做报表，需要实现一个比较特殊的打印：针对不同患者的药费记录，打印不同的清单，并且支持一次打印多个患者的记录。其效果看起来应该像下面这个样子：
如上所述，使用弱智的水晶报表，就会遇到如何构造数据源的问题，由于不同患者的药费记录和遗嘱记录都不同，而且整体上需要一个患者一个清单，所以其数据源只能为一个数组，而不是简单的DataTable。小弟一向对大且笨拙的CrystalReport不感冒，再加上对GDI+比较痴迷，索性费点功夫，使用GDI+来打印上述报表。
首先需要构造数据源，创建一个ArrayList对象a，然后再把每个患者需要打印的东东保存为一个ArrayList放入ATotal中。

a.Clear();
