复制代码 代码如下:
/// 构造随机数 种子
static int GetRandomSeed()
{
            byte[] bytes = new byte[4];
            System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider();
            rng.GetBytes(bytes);
            return BitConverter.ToInt32(bytes, 0);
}
///  生成随机 数
static int rnd() 
{    
            Random ran = new Random(GetRandomSeed());        
            int cnt = ran.Next(0,59);
            return cnt;
 }
