web.config文件中配置access

 Web.config 中:

    <appSettings>
        <add   key= "OleDbConnectionString "   value= "Provider=Microsoft.Jet.OLEDB.4.0;Data   Source= "/>
        <!--请根据您的数据库路径修改以下这句-->
        <add   key= "AccessDbPath "   value= "DataBase/OA.mdb "   />
    </appSettings>

调用：
                string   DataPath   =   HttpContext.Current.Server.MapPath( "~/ "   +   ConfigurationSettings.AppSettings[ "AccessDbPath "]);
                OleDbConnection   Conn   =   new   OleDbConnection( "Provider=Microsoft.Jet.OLEDB.4.0;Data   Source= "   +   DataPath   +   " ");
                Conn.Open();
