C# MySql 读写数据的示例代码
通过MySql connector net组件操作MYSQL数据库：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using MySql.Data.MySqlClient;
namespace DatabaseWindowsApp1
{
public partial class Form1 : Form
{
private static string DB_CON_STR = "server=localhost;uid=root;pwd=root;database=test";
public Form1()
{
InitializeComponent();
}
private void bindListView()
{
listView1.Clear();
listView1.Columns.Add("ID");
listView1.Columns.Add("Student");
MySqlConnection con = new MySqlConnection(DB_CON_STR);
con.Open();
MySqlCommand cmd = new MySqlCommand("student");
cmd.Connection = con;
cmd.CommandType = CommandType.TableDirect;
MySqlDataReader dr = cmd.ExecuteReader(CommandBehavior.Default);
while (dr.Read())
{
System.Console.WriteLine(dr.GetInt32(0).ToString() + ": " + dr.GetString(1));
// Create three items and three sets of subitems for each item.
ListViewItem item1 = new ListViewItem(dr.GetInt32(0).ToString());
// Place a check mark next to the item.
item1.Checked = true;
item1.SubItems.Add(dr.GetString(1));
//Add the items to the ListView.
listView1.Items.Add(item1);
}
dr.Close();
con.Close();
}
private void Form1_Load(object sender, EventArgs e)
{
bindListView();
}
private void button1_Click(object sender, EventArgs e)
{
MySqlConnection con = new MySqlConnection(DB_CON_STR);
con.Open();
MySqlCommand cmd = new MySqlCommand("INSERT INTO student (name) value (@name)");
cmd.Connection = con;
cmd.Prepare();
cmd.Parameters.AddWithValue("@name", textBox1.Text);
int i = cmd.ExecuteNonQuery();
if (i > 0)
MessageBox.Show("插入记录成功");
bindListView();
}
}
}
数据库结构：
mysql> describe class;
+-------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+----------------+
| sid | int(11) | NO | PRI | NULL | auto_increment |
| name | varchar(32) | YES | | NULL | |
+-------+-------------+------+-----+---------+----------------+
mysql> describe student;
+-------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+----------------+
| sid | int(32) | NO | PRI | NULL | auto_increment |
| name | varchar(32) | YES | | NULL | |
+-------+-------------+------+-----+---------+----------------+
