C#中的try catch finally

try中的程序块是有可能发生错误的程序块，catch中的程序块是当发生错误的时候才会执行的代码块，finally中的程序块是无论是否发生错误都会执行的代码块。

示例程序：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace Sample_01_CA {     public class Complex     {         static void Main(string[] args)         {             int i = 2008;             int j = 0;             try             {                 int result = i / j;             }             catch             {                 Console.WriteLine("J变量的值为0");             }             finally             {                 Console.WriteLine(j.ToString());             }             Console.Read();         }     }; }

程序输出为：

J变量的值为0
