1.访问云服务器：云服务器端需在防火墙设置中添加mysql协议规则(放开端口默认为3306)。
2.访问云服务器：修改云服务器数据库访问权限
3.c#连接实例
try
{
DataTable dt = new DataTable();
string ConnectionStr = "server=" + "xxx.xxx.xxx.xxx" + ";User ID=root;Password=123456;database=mydatabase;Allow User Variables=True;SslMode=none;";
MySqlConnection conn = new MySqlConnection(ConnectionStr);
conn.Open();
string sSQL = "select *from mytable2";
MySqlCommand cmd = new MySqlCommand(sSQL, conn);
MySqlDataReader dr = cmd.ExecuteReader();
if (dr.HasRows)
{
//读取MySqlDataReader里的内容
dt.Load(dr);
}
//关闭对象和连接
dr.Close();
this.dataGridView1.DataSource = dt;
}
catch(Exception ee)
{
}
4.my.ini文件实例
