  • 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:

    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

    0
