重写了微软提供SQLHelper(共用的数据库调用接口） 1把SqlHelper的connectionString做成一个全局量，统一设置数据库连接字符串 2增加了返回特定表名的DataSet的各接口。 可在项目的config文件设置数据库连接字符串 private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"] 当然可以把数据库连接方法修改后直接用。-rewritten Microsoft SQLHelper (shared database Call Interface) a SqlHelper the connectionString caused an overall volume, uniform database connections increased by two strings to the specific name of the table in the DataSet interface. In the config files set database connection string private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings [ "ConnectionString"] lt; !-- Application specific settings-- gt; Lt; AppSettingsgt; Lt; Add key

实验说明   实验所用英文文本为 /HaffmanfT 下的a.txt文件，原文为： South Korea’s top court ruled on Thursday that Japan’s Mitsubishi Heavy Industries Ltd must compensate 28 South Koreans for their forced labor during World War Two, a ruling that drew an immediate rebuke from Tokyo. The decision echoed the Supreme Court’s landmark verdict last month that ruled in favor of South Koreans seeking compensation from Japan’s Nippon Steel & Sumitomo Metal Corp. for their wartime forced labor. The court upheld a 2013 appeals court decision that Mitsubishi must pay 80 million won ($71,000) to each of the 23 plaintiffs in compensation. In a separate

一． 问题描述很多涉及图上操作的算法都是以图的遍历为基础的。试写一个程序，演示在连通的无向图上访问全部节点的操作。二． 基本要求以邻接多重链表为存储结构。实现连通无向图的深度和广度优先遍历。以用户指定的节点为起点，分别输出每种遍历下的节点访问序列和相应生成树的边集。-one. Description many issues involving maps of algorithms are to traverse the map-based. A written test procedures, demonstrating the connectivity of undirected graph visit all the nodes on the operation. 2. Adjacent to the basic requirements for storage of multiple linked list structure. Connectivity to the map without the depth and breadth- first traversal. User specified nodes as a starting point, the output of each node traversal visit Spanning Tree sequence and the corresponding set of edges.
