一个简单的公交查询管理系 d 统，采用最短路算法，利用odbcapi函数访问数据库。 -a simple inquiry Bus Marketing Management-d, the most shorted algorithm, use odbcapi function access to the database.

C#中实现最短路，该图算法描述的是这样的场景：图由节点和带有方向的边构成，每条边都有相应的权值，路径规划（最短路径）算法就是要找出从节点A到节点B的累积权值最小的路径。-achieve the most short-circuit, the algorithm described in the plan that is the scene : map with nodes and from the direction of the edges, and each side has a corre
