CheckSameExit(temp_TID, i_TID)为何卡住了，找了那么久就是找不出原因

private bool CheckSameExit(string[] temp, int length)//检查数组中是否存在相同元素 存在返回true反之返回false

                    }
                }
            }
            return false;
        }

        private bool IsChongTu(Arng[,] GeTi, int e, int r, int edu)//冲突检测函数 冲突返回true
