答：函数是这样用,比如100至999的随机数 Random ran=new Random(); int RandKey=ran.Next(100,999); 不过这样会有重复,可以给Random一个系统时间做为参数，以此产生随机数，就不会重复了 System.Random a=new Random(System.DateTime.Now.Millisecon...

答：RAND( ) 说明 若要生成 a 与 b 之间的随机实数，请使用： RAND()*(b-a)+a 如果要使用函数 RAND 生成一随机数，并且使之不随单元格计算而改变，可以在编辑栏中输入“=RAND()”，保持编辑状态，然后按 F9，将公式永久性地改为随机数。 示例 如果您将...
