C#连接MySQL数据库，进行增删改查

一、创建数据库 学生表

create database test;

create table student(
	sNo varchar(50) primary key,
	sName varchar(50) not null
)

补充：数据的增删改查相关操作

insert into student values('01','张三');

update student set sName="李四" where sNo="01";

delete from student where sNo="01";

select * from student; 

二、引用MySql程序集

C# 链接MySQL数据库的方式：

具体操作：

vs 解决方案 ，选择 “引用”，右键添加 对应.NET版本 文件路径的 MySql.Data.dll 动态库。

三、 进行数据的增删改查

示例：

static void SQLOperator() {
    MySqlConnection msc = null;
    MySqlCommand msco = null;
    try {
        //1.连接数据库  
        string cStr = "server=127.0.0.1;port=3306;user=root;password=1234;database=test";
        msc = new MySqlConnection(cStr);
        msc.Open();
        //2.创建数据库操作对象并进行具体操作
        //2.1 增删改
        string sqlInsert = "insert into student values('02','李四');";
        //string sqlUpdate = "update student set sName='王天霸' where sNo='02';";
        //string sqlDelete = "delete from student where sNo='02';";
        msco = new MySqlCommand(sqlInsert, msc);
        msco.ExecuteNonQuery();
        //2.2 查
        string sqlQuery = "select * from student;";
        msco = new MySqlCommand(sqlQuery, msc);
        MySqlDataReader msdr=msco.ExecuteReader();
        while (msdr.Read()) {
            Console.Write(msdr[0].ToString() + "  " + msdr[1].ToString() + '\\n');
        }
    } catch {

    } finally {
        msco.Dispose();
        msc.Close();
    }
}
