    public static string GenerateRandomNumber(int Length)
    {
        System.Text.StringBuilder newRandom = new System.Text.StringBuilder(100);
        Random rd = new Random();
        for (int i = 0; i < Length; i++)
        {
            newRandom.Append(constant[rd.Next(100)]);
        }
        return newRandom.ToString();
    }
}

 你写的太麻烦，这么写：
string static metachar = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+|-=\\{}[]:\";'<>?,./~`";
public static string GenerateRandomNumber(int Length)
{
    return string.Concat(metachar.OrderBy(x => Guid.NewGuid()).Take(Length));
}
