aspx页面写数据库连接connectionstring怎么写？

Question

你好！我用vs2012开发mvc4程序，其中用到了aspx页面，后台数据库就是sqllocaldb
现在我在系统的odbc也配好了，名字就叫sqllocaldb，请问在aspx里怎么写connectionstring?

 string ConnectString = "Data Source=sqllocaldb";
            SqlConnection con = null;
            SqlCommand cmd = null;
            SqlDataReader str = null;
            try
            {               
                    con = new SqlConnection(ConnectString);      
                    //连接到数据库
                    cmd = con.CreateCommand();
                    cmd.CommandText = "select SalesId, SalesName,SalesPhone,SalesEmail from SalesTable";
                    //T-SQL语句    
                    con.Open();                                 
                    //创建连接后需要用Open打开连接，结束后要关闭连接，及时释放资源
                    str = cmd.ExecuteReader();

           using System.Data.Odbc;

           var con = new OdbcConnection();
            if (con != null)
                con.Close();
            try
            {               
                    con.ConnectionString =
                                   "Dsn=sqllocaldb;" +
                                   "Uid=;" +
                                   "Pwd=;";     
                    //连接到数据库
                    con.Open();
                    var cmd = con.CreateCommand();
                    cmd.CommandText = "select SalesId, SalesName,SalesPhone,SalesEmail from SalesTable";
                  var str = cmd.ExecuteReader();
