今天百无聊赖的成果

照着UML图，随便写了个Abstract Factory模式

Load assembly的时候有点不一样，因为那个目录很怪很长，是个临时目录，所以我用location得到了它。很奇怪阿。怎么放那里，看来vs2008是不一样阿。

 string location = Assembly.GetAssembly(Type.GetType(factoryName)).Location; 
 factory = (IFactory)Assembly.LoadFile(location).CreateInstance(factoryName);

代码没啥说的，就是连连手而已。小时候看图说话，现在看图写代码，哈哈。
