我是一名新秀,刚学C#,在连接数据库的时候老师出错,望指点,连接代码如下:
 SqlConnection thisConnection = new SqlConnection(
                @"Server=(local);Integrated Security=True;" +
                "Database=northwind");
            //打开连接
            thisConnection.Open();
            //创建命令
            SqlCommand thisCommand = thisConnection.CreateCommand();
            //查询语句
             =
                "SELECT CustomerID ,CompanyName from Customers";
            //执行DataReader
            SqlDataReader thisReader = thisCommand.ExecuteReader();
            //while there are rows to read
            while (thisReader.Read())
            {
                //输出ID 和 NAME 行
                Console.WriteLine("\t{0}\t{1}",
                    thisReader["CustomerID"], thisReader["CompanyName"]);
            }
            //关闭 Reader
            thisReader.Close();
            //关闭连接
            thisConnection.Close();
            Console.WriteLine("Programe finished ,press enter/return to continue");
            Console.ReadKey();
