C#连接MySQL数据库方法

C#连接MySQL数据库方法
1、用MySQLDriverCS连接MySQL数据库先下载和安装MySQLDriverCS，地址：
http://sourceforge.net/projects/mysqldrivercs
在安装文件夹下面找到MySQLDriver.dll，然后将MySQLDriver.dll添加引用到项目中
注：我下载的是版本是 MySQLDriverCS-n-EasyQueryTools-4.0.1-DotNet2.0.exe

        private void Form1_Load(object sender, EventArgs e)
        {
            MySQLConnection conn = null;
            conn = new MySQLConnection(new MySQLConnectionString("localhost", "inv", "root", "831025").AsString);
            conn.Open();
            MySQLCommand commn = new MySQLCommand("set names gb2312", conn);
            commn.ExecuteNonQuery();
            string sql = "select * from exchange ";
            MySQLDataAdapter mda = new MySQLDataAdapter(sql, conn);
            DataSet ds = new DataSet();
            mda.Fill(ds, "table1");
