MariaDB最近越来越热,于是也下了个来捣腾捣腾。我下的是mariadb-10.0.4-win32.msi,但是安装完后,想用C#进行连接时,发现没有可以用的驱动。网上找了一番后,说是MaraiDB兼容MySQL,所以可以用MySQL的驱动来连接。不过,有文提到MariaDB5.5相当于MySQL的5.5,,而MariaDB10.0.4相当于MySQL5.6,而MySQL现在已经是6.7了,所以下载MySQL驱动的时候要特别注意,还有要注意的是mariadb是32还是64位的,搞错了,连接会出问题。

在下MySQL驱动的时候本来想在官网下的,但是要帐号,所以就另找了个镜像点下。这是镜像点,我下的是MySQL-connector-net-5.2.7。

下面是具体实现的代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using MySql.Data.MySqlClient;

namespace MariaDBTest
{
    public partial class FormMain : Form
    {
        public FormMain()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        MySqlConnection connection_;
        private void buttonOpenConnect_Click(object sender, EventArgs e)
        {
            string connectionStr = "server=localhost;user id=root;password=abc;database=test";
            connection_ = new MySqlConnection(connectionStr);
            connection_.Open();
            MessageBox.Show("Connect OK!");
        }

        private void buttonSelect_Click(object sender, EventArgs e)
        {
            if (connection_ == null)
            {
                MessageBox.Show("Please open connect!");
                return;
            }
            string sql = "SELECT * FROM MyTable";
            MySqlDataAdapter adapter = new MySqlDataAdapter(sql, connection_);
            DataTable dataTable = new DataTable();
            adapter.Fill(dataTable);
            dataGridViewMariaDB.DataSource = dataTable;
        }

        private void buttonCloseConnect_Click(object sender, EventArgs e)
        {
            if (connection_ != null)
            {
                connection_.Close();
                MessageBox.Show("Connect Close!");
            }
        }

        private void buttonInsert_Click(object sender, EventArgs e)
        {
            if (connection_ == null)
            {
                MessageBox.Show("Please open connect!");
                return;
            }
            int no = DateTime.Now.Second;
            int sum = DateTime.Now.Millisecond;
            string sql = string.Format("INSERT INTO MyTable (`NO`,`Sum`) VALUES({0},{1});", no, sum);
            MySqlCommand command = new MySqlCommand(sql, connection_);
            int affectLines = command.ExecuteNonQuery();

            MessageBox.Show("Affect " + affectLines.ToString() + " line");

        }

        private void buttonDelete_Click(object sender, EventArgs e)
        {
            if (connection_ == null)
            {
                MessageBox.Show("Please open connect!");
                return;
            }
            int no = Convert.ToInt32(textBoxNO.Text);
            string sql = string.Format("DELETE FROM MyTable WHERE `NO`={0}", no);
            MySqlCommand command = new MySqlCommand(sql, connection_);
            int affectLines = command.ExecuteNonQuery();

            MessageBox.Show("Affect " + affectLines.ToString() + " line");

        }

   
    }
}

这里有几点需要注意的:
