private static object GetInstance(string CacheKey) { object objType = DataCache.GetCache(CacheKey); if (objType ==null) { try { objType = Assembly.Load(DALFactory._path).CreateInstance(CacheKey); DataCache.SetCache(CacheKey, objType); } catch (Exception ex) { throw ex; } } return objType; } 中的objType = Assembly.Load(DALFactory._path).CreateInstance(CacheKey);objType怎么为null 啊 DALFactory._path和CacheKey都有值 怎么Assembly.Load没有用啊
