简单的取c#（flex）固定位数的随机数

c#固定位数的随机数：

private string rd()
    {
        try
        {
            StringBuilder sb = new StringBuilder();
            Random rd = new Random(DateTime.Now.Millisecond);
            for (int i = 0; i < 7; i++)
            {
                char c = (rd.Next(0, 9).ToString()[0]);
                sb.Append(c.ToString());
            }
            return sb.ToString();
        }
        catch
        {
            return "1234567";
        }
    }

flex固定位数的随机数：

private function rd():String
  {
   var rd:int = int(Math.random()*9999999);
   if(rd < 1000000)
    rd+=1000000;
   return rd.toString();
  }
