1.在用windows模式登陆sql server 数据库 简历一个student的数据库,然后新建查询:
- create table student
- (
- id int auto_increment primary key,
- name char(10) not null,
- sex char(10) not null,
- age char(10) not null,
- )
复制代码
2.在vs中新建一个项目,输入一下代码:
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Text;
- using System.Threading.Tasks;
- using System.Data;
- using System.Data.SqlClient;
- namespace ConsoleApplication1
- {
- class Program
- {
- static void Main(string[] args)
- {
- string connSting;
- connSting = "server=localhost;database=student;Integrated Security=True ";
- SqlConnection sConn = new SqlConnection(connSting);
- try
- {
- sConn.Open();
- }
- catch (Exception ex)
- {
- Console.WriteLine("链接错误:" + ex.Message);
- }
- string sqlMessage=null;
- sqlMessage = "select * from student";
- SqlCommand sCmd = new SqlCommand(sqlMessage, sConn);
- SqlDataReader sdr = null;
- try
- {
- sdr = sCmd.ExecuteReader();
-
- Console.WriteLine(" 姓名 性别 年龄 ");
- while (sdr.Read())
- {
- Console.WriteLine(sdr["name"] +""+ sdr["sex"]+"" + sdr["age"]);
- }
- sConn.Close();
- }
- catch (Exception ex)
- {
- Console.WriteLine(ex.Message);
- }
- Console.ReadLine();
- }
- }
- }
复制代码
3.运行结果将会显示数据库中的数据
