匿名方法的使用
匿名方法相信很多人都听过，它是C#2.0的一个新特性，顾名思义，匿名方法就是没有名称的方法。那么在C#中的匿名方法有哪些好处，在C#中如何使用呢？匿名方法最明显的好处就是可以降低另写一个方法的工作量，另外一个好处就是可以访问调用者的变量，降低传参数的复杂度，下面就通过一些使用例子来具体看看。
1、在事件中使用匿名方法
下面是一个定时器的小例子，我们常规的写法如下：
<div style="border-right: #cccccc 1px solid; padding-right: 5px; border-top: #cccccc 1px solid; padding-left: 4px; font-size: 13px; padding-bottom: 4px; border-left: #cccccc 1px solid; width: 98%; padding-top: 4px; border-bottom: #cccccc 1px solid; background-color: #eeeeee;">http://www.cnblogs.com/Images/OutliningIndicators/ContractedBlock.gifhttp://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif常规写法
