首先配置好你的MariaDb,創建test數據庫，在test里創建MyTable表，腳本如下（通過HeidiSQL導出的腳本）：
-- --------------------------------------------------------
-- 主機: 172.16.40.153
-- 服務器版本: 5.5.5-10.0.4-MariaDB-1~wheezy-log - mariadb.org binary distribution
-- 服務器操作系統: debian-linux-gnu
-- HeidiSQL 版本: 8.1.0.4545
-- --------------------------------------------------------
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET NAMES utf8 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
-- 導出 test 的數據庫結構
DROP DATABASE IF EXISTS `test`;
CREATE DATABASE IF NOT EXISTS `test` /*!40100 DEFAULT CHARACTER SET latin1 */;
USE `test`;
-- 導出 表 test.MyTable 結構
DROP TABLE IF EXISTS `MyTable`;
CREATE TABLE IF NOT EXISTS `MyTable` (
`id` int(11) NOT NULL,
`username` varchar(32) DEFAULT NULL,
`password` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
-- 正在導出表 test.MyTable 的數據：~0 rows (大約)
DELETE FROM `MyTable`;
/*!40000 ALTER TABLE `MyTable` DISABLE KEYS */;
INSERT INTO `MyTable` (`id`, `username`, `password`) VALUES
(1, '2013/10/13', '1f11082e-7c23-4ffd-bfd2-67b0a58d'),
(25, '2013/10/13', 'fc52bd01-474b-4fa4-86f1-18d3a3c7'),
(32, '2013/10/13', '1078f559-3e39-4b7d-bcab-0286c7f4'),
(58, '2013/10/13', '95ee6ce5-fcef-4785-bd0d-3482e6de');
/*!40000 ALTER TABLE `MyTable` ENABLE KEYS */;
/*!40101 SET SQL_MODE=IFNULL(@OLD_SQL_MODE, '') */;
/*!40014 SET FOREIGN_KEY_CHECKS=IF(@OLD_FOREIGN_KEY_CHECKS IS NULL, 1, @OLD_FOREIGN_KEY_CHECKS) */;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
C#代碼如下：包含了簡單的新增刪除查詢，工具是vs2012版本，一定要下載mysql-connector-net，我選擇的是最新的版本
別忘了添加引用
using MySql.Data.MySqlClient;
MySqlConnection connection_;
private void buttonOpenConnect_Click(object sender, EventArgs e)
{
//string connectionStr = "server=127.0.0.1;user id=root;password=;database=test";
string connectionStr = "server=172.16.40.153;user id=root;password=123456;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 id = DateTime.Now.Second;
string username = DateTime.Now.ToShortDateString();
string password = Guid.NewGuid().ToString();
string sql = string.Format("INSERT INTO MyTable (`id`,`username`,`password`) VALUES({0},'{1}','{2}');", id, username, password);
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 id={0}", no);
MySqlCommand command = new MySqlCommand(sql, connection_);
int affectLines = command.ExecuteNonQuery();
MessageBox.Show("Affect " + affectLines.ToString() + " line");
}
