从配置文件获取信息

基础方法：

        /// <summary>
        /// 通过Singleton模式返回当前实例
        /// </summary>
        public static T Instance(string className)
        {

            if (m_instance == null)
            {
                lock (m_lock)
                {
                    if (m_instance == null)
                    {
                         

                        NameValueCollection nc = (NameValueCollection)ConfigurationManager.GetSection("CLOUDS/BussValue");
                        string bussness = nc[className].ToString();
                        m_instance = (T)Type.GetType(bussness).GetConstructor(System.Type.EmptyTypes).Invoke(null);
                    }
                }
            }
            
            return m_instance;
        }

调用方法：

        /// <summary>

            DataSet ds = IBussFactory<BussLogisticsDispatchingRange>.Instance("LogisticsDispatchingRange").GetProvinceWithLogisticsDS(logisticsDispatchingRangeModel);
