.net连接Mysql封装

微软的visual studio没有自带连接Mysql的驱动，要去网上下载一个mysql-connector-net-6.4.3驱动，然后安装就可以使用。

下面是我封装好的连接数据库的类，直接调用即可。

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>
      /// 获取数据库连接桥
      /// </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;远程连接的

               
                //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)
                {
                    _connection.Close();
                    _connection.Open();
                }
                return GetConnection._connection;
            }
