微軟的visual studio沒有自帶連接Mysql的驅動，要去網上下載一個mysql-connector-net-6.4.3驅動，然后安裝就可以使用。
下面是我封裝好的連接數據庫的類，直接調用即可。
代碼如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using MySql.Data.MySqlClient;
namespace DAL
{
public class GetConnection
    {
        private static MySqlConnection _connection;
      /// <summary>
      /// 獲取數據庫連接橋
      /// </summary>
        private static MySqlConnection Connection
        {
            get
            {
               //string connectionString = ConfigurationManager.AppSettings["ConnectionString"];
                string connectionString = "server=localhost;user id=root; password=root; database=system; pooling=false";
                //server=222.222.222.222;port=3306;uid=user;pwd=;database=basename;遠程連接的
                //string connectionString = "Data Source=202.192.72.22;Initial Catalog=wwj;Persist Security Info=True;User ID=wwj;Password=wwj123";
                if (_connection == null)
                {
                    _connection = new MySqlConnection(connectionString);
                    _connection.Open();
                }
                if (_connection.State == ConnectionState.Closed)
                {
                    _connection.Open();
                }
                if (_connection.State == ConnectionState.Broken)
