你是想产生62位内任意数字大小写字母的随机数,输出6个字符吧。- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Text;
- namespace T1论坛
- {
- class Program
- {
- static void Main(string[] args)
- {
- //调用方法
- string str = GenerateRandom(6);
- Console.WriteLine(str);
- Console.ReadKey();
- }
- //定义一个常量
- static char[] constant =
- {
- '0','1','2','3','4','5','6','7','8','9',
- 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',
- 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'
- };
- //定义生成随机数的方法
- static string GenerateRandom(int Length)
- { //类的实例化
- System.Text.StringBuilder newRandom = new System.Text.StringBuilder(62);
- Random rd = new Random();
- //循环产生随机数
- for (int i = 0; i < Length; i++)
- {
- newRandom.Append(constant[rd.Next(62)]);
- }
- //返回值
- return newRandom.ToString();
- }
- }
- }
