C#中的try catch finally（链接）

下面这篇微软的官方文档，详细讲述了C#中如何使用try catch finally来处理异常：

Exception-handling statements - throw, try-catch, try-finally, and try-catch-finally

其中这个地方有说到，不管是在try代码块中发生了异常，还是在catch代码块中发生了异常，finally代码块的代码都会执行：

When an exception is handled by a catch block, the finally block is executed after execution of that catch block (even if another exception occurs during execution of the catch block).

The try-catch-finally statement

下面这篇微软的官方文档中还有提到，当一个异常（Exception）被抛出（throw）后，抛出异常那一行之后跟随的代码就都不会被执行了：

Causes of exceptions

Control never reaches the statement immediately following the throw.
