主要代码如下:

 //连接字符串
 string strConn="user id=sa;password=123456;initial catalog=MyDb;Server=192.168.47.144,1433;Connect Timeout=10";
               
                //创建连接对象
                SqlConnection objConn = new SqlConnection(strConn);

                try
                {       //开始连接数据库
                        objConn.Open();

                        //执行SQL语句
                        string sql = "SELECT * FROM tb_People";
                        SqlCommand sqlCom = new SqlCommand(sql,objConn);

                        //创建数据读取器对象,注意：该对象只能顺序读取记录
                        SqlDataReader sqlDataReader = sqlCom.ExecuteReader();

                        //循环输出记录
                        int i = 1;
                        while(sqlDataReader.Read()){

                                Console.WriteLine("\n表tb_People第{0}条记录为:{1}{2}",
                                        i,
                                        sqlDataReader.GetValue(0),
                                        sqlDataReader.GetValue(1));
                                i++;
                        }
            
                        //断开与数据库的连接...
                        objConn.Close();
                }
                //捕获异常...
                catch(SqlException e){

                        objConn.Close();

                        Console.WriteLine(e.Message+e.ErrorCode);

                }
