        {

            string MyConString = "SERVER=localhost:3316;" +

                "UID=user;" +

            MySqlConnection connection = new MySqlConnection(MyConString);
            connection.Open();
            // ...
            connection.Close();

Answer 1

您需要在连接字符串中将Port指定为单独的参数，并且密码密钥看起来像是“Pwd”而不是“Password”。

有关确切语法的帮助，请参阅connectionstrings.com。

Answer 2

这是我用来通过MySql.Data.dll版本6.1.2.0连接的字符串格式

server = {0};用户ID = {1};密码= {2};数据库= {3}; port = {4}

所以你的连接字符串应该是

server = localhost; user id = user; password = password; database = mydb; port = 3316
