2.Oracle自己提供的方法:using Oracle.DataAccess.Client;
前提条件:安装oracle或者oracle client以及安装 Oracle Client 。
··1.在VS2010新建控制台应用程序(C#);
··2.右键、引用,在.NET/组件中选择Oracle.DataAccess.Client;如果找不到则选择 浏览,进入到oracleclient的安装目录寻找 Oracle.Data.Access.dll (典型目录为:E:\app\Administrator\product\11.2.0\client_1\ODP.NET\bin\2.x\Oracle.Data>Access.dll)
··3.程序中添加引用:using Oracle.DataAccess.Client;
