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(); }
