一、先创建一张“学生”表（注，本文用的数据库是Mysql）
CREATE TABLE `t_student` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(6) NOT NULL DEFAULT ‘‘ COMMENT ‘姓名‘, `sex` bit(1) NOT NULL DEFAULT b‘0‘ COMMENT ‘性别，0表示女，1表示男‘, `age` tinyint(3) NOT NULL DEFAULT ‘0‘ COMMENT ‘年龄‘, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT=‘学生‘;
二、先写一个“”类，里面实现数据库连接相关
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//
using MySql.Data.MySqlClient;
using System.Data;
namespace Dapper_demo
{
/// <summary>
/// 连接类
/// </summary>
public class Dbhelper
{
/// <summary>
/// Mysql连接字符串
/// </summary>
public static string MysqlConnectionString = "server=localhost;user id=root;password=root;database=dapper;port=3306;character set=utf8";
private static IDbConnection connection;
/// <summary>
/// 获取db连接
/// </summary>
/// <returns></returns>
public static IDbConnection GetConnection()
{
IDbConnection myConn = new MySqlConnection(MysqlConnectionString);
string connectionString = myConn.ConnectionString;
if (connection == null)
{
connection = new MySqlConnection(connectionString);
connection.Open();
}
else if (connection.State == System.Data.ConnectionState.Closed)
{
connection.Open();
}
else if (connection.State == System.Data.ConnectionState.Broken)
{
connection.Close();
connection.Open();
}
return connection;
}
}
}
三、插入单条数据
using (var conn = Dbhelper.GetConnection())
{
int res = conn.Execute("insert into t_student(`name`,`sex`,`age`) values(@name,@sex,@age)", new { name = "张三", sex = 1, age = 23 });
Console.WriteLine("成功插入" + res + "条数据");
}
四、插入多条数据
using (var conn = Dbhelper.GetConnection()) { int res = conn.Execute("insert into t_student(`name`,`sex`,`age`) values(@name,@sex,@age)", new[] { new { name = "张三", sex = 1, age = 23 }, new { name = "李四", sex = 1, age = 30 } } ); Console.WriteLine("成功插入" + res + "条数据"); }
