C#--使用Finally

时间：2011-05-08 来源：孤独的猫

C#中可以用try..catch..Finally进行异常处理，try后面跟要执行的语句，catch为如有异常，对异常进行处理，Finally做清理工作，这部分必须执行，如下示例：

 1 /*
 2   Example13_1.cs illustrates a try, catch, and finally block
 3  */
 4 
 5 using System;
 6 
 7 class Example13_1
 8 {
 9 
10   public static void Main()
11   {
12 
13     try
14     {
15 
16       // code that throws an exception
17       int zero = 0;
18       Console.WriteLine("In try block: attempting division by zero");
19       int myInt = 1 / zero;  // throws the exception
20       Console.WriteLine("You never see this message!");
21 
22     }
23     catch
24     {
25 
26       // code that handles the exception
27       Console.WriteLine("In catch block: an exception was thrown");
28 
29     }
30     finally
31     {
32 
33       // code that does any cleaning up
34       Console.WriteLine("In finally block: do any cleaning up here");
35 
36     }
37 
38   }
39 
40 }
