【ASP.NET】多线程操作全局变量时候的处理。

        /// <param name="userUid">用户帐号</param>

        /// <returns></returns>
        public List<LPFunction> QueryAllPrivilege(string userUid,string appCode)
        {
            //线程唯一性操作，保证其他线程调用时候获取到的ApplicationCode不会被篡改。
            lock (RuntimeConfigLock)
            {
                RuntimeConfig.Instance.ApplicationCode = appCode;
                QueryBUAPrivilegeAllList(userUid,string.Empty);

            }
            return lpFunctionList;
        }
