由错误的方法中得到的

- -!今天做了件糊涂事,居然忘记用sp来直接cross表格来取值。不过由此也得到一个方法：

        private struct SLocation
        { 
            public string  name; 
            public int ID; 
        } 
        
        private ArrayList GetLocationArrayList()
        {
            if (this._dsLocation.Tables.Count<=0)
            {
                this._dsLocation = this._loc.GetLocationList();
            }
            DataTable _dt   = this._dsLocation.Tables[0];
            ArrayList _al   = new ArrayList();
            SLocation _stcloc = new SLocation();
            foreach (DataRow _dr in _dt.Rows)
            {
                _stcloc.ID   = Convert.ToInt32(_dr["LOCATION_ID"]);
                _stcloc.name = _dr["LOCATION_NAME"].ToString();
                _al.Add(_stcloc);
            }
            return _al;
        }

        private String GetLocationNameByID(int ID)
        {
            if (this._alLocation.Count<=0)
            {
                this._alLocation  = this.GetLocationArrayList();
            }
            IEnumerator _emun   = _alLocation.GetEnumerator();
            SLocation _stcloc   = new SLocation();
            String _locName     = string.Empty;
            for (int i=0;i<_alLocation.Count-1;i++)
            {
                _emun.MoveNext();
                _stcloc = (SLocation)_emun.Current;
                if (_stcloc.ID  == ID)
                {
                    _locName    = _stcloc.name;
                    break;
                }
            }
            return _locName;
        }

先声明一个结构，再将结构做为object放入arraylist.
