C#对于sql server数据库的简单操作

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,   

)

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();

        }

    }

}

3.运行结果将会显示数据库中的数据
