c#操作sqlserver數據庫的簡略示例

c#操作sqlserver數據庫的簡略示例。本站提示廣大學習愛好者：（c#操作sqlserver數據庫的簡略示例）文章只能為提供參考，不一定能成為您想要的結果。以下是c#操作sqlserver數據庫的簡略示例正文

1.在用windows形式上岸sql server 數據庫 簡歷一個student的數據庫，然後新建查詢：

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中新建一個項目，輸出一下代碼：

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("鏈接毛病:" + 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   性別   年紀 ");
                while (sdr.Read())
                {
                    Console.WriteLine(sdr["name"] +""+ sdr["sex"]+"" + sdr["age"]);
                }
                sConn.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadLine();
        }
    }
}
