C#生成随机数字与字母组合实例

常见的随机组合可用于验证码、券码、临时识别码等用途，先把代码实例备份，以备不时之需，希望也能帮助到浏览到该篇文章的朋友们。

代码实例：

        private 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'};

        public static string GenerateRandomNumber(int Length)
        {
            System.Text.StringBuilder newRandom = new System.Text.StringBuilder(62);
            Random rd = new Random();
            for (int i = 0; i < Length; i++)
            {
                newRandom.Append(constant[rd.Next(62)]);
            }
            return newRandom.ToString();
        }

调用方法：

var str=GenerateRandomNumber(int.Parse(i));
