UML类关系

UML中涉及依赖、关联、聚合、组合和泛化这五种关系，耦合度依次递增。

依赖

依赖关系使用虚线加箭头表示：

What The Fuck!

这是一个操蛋的周一，这是天天加班到八点的第一个周一。

加班到八点，意味着：

1.我没法去接我女朋友。

2.这段时间肯定不能做饭了。

哈希表简述

在.NET Framework中，Hashtable是System.Collections命名空间提供的一个容器，用于处理和表现类似keyvalue的键值对，其中key通常可用来快速查找，同时key是区分大小写；value用于存储对应于key的值。Hashtable中keyvalue键值对均为object类型，所以Hashtable可以支持任何类型的keyvalue键值对。

最近公司开始做新的项目，需要对软件框架进行选择。现在整理了一些常用的.NET框架，用于以后的工作和学习。

IOC容器框架

Untiy框架

Unity 是一个轻量级、可扩展的依赖注入容器（Dependency Injection Container），其支持截取、构造函数注入、属性注入和方法调用注入等。可以利用 Unity 通过多种方式进行应用程序组件间的解耦，从而最大化组件的一致性，并简化设计、实施、测试和管理等。
