从钱龙数据中读取股票权息信息导入到数据库

前面写了如果读股票代码和日线数据，下面是如何读股票的权息信息。

钱龙中权息数据存储在QLDATA\history\shase\weight和QLDATA\history\sznse\weight目录下，每个文件对应一只股票。

与前文一样，只贴核心代码：

                if (strTemp.ToUpper().EndsWith(".WGT"))
                {
                    strStockCode = strTemp.Substring(0, strTemp.Length - 4) ;
                    break;
                }
            }
            Debug.Assert(strStockCode != null);
