C#+WPF+oracle 检查文件服务器上文件是否存在
现在有个需求，有个FTP/HTTP网站上有一堆文件，记录存在数据库。
但根本无法知道那些文件在数据库中不存，那些文件在库里面，但不存在实体文件。
现在做了个程序，可以做到读取数据库文件列表，然后检查网上链接是否有效，也可以反向检查。

///一般都是使用OLEDB或者是.NET中提供的OracleClient来进行连接。而微软也宣称，从.NET4.0开始放弃对OracleClient的支持，但不会删除，标记为不建议使用。 所以可以使用ORACLE提供的ADO.NET访问组件ODP.NET，组件的名字为OracleDataAccess.dll，oracle的使用和OracleClient完全一样，在程序中添加DLL引用就可以使用。
