Connectiong to Mysql Database

Question

How can I connect my Sql Database with my application?
Actually I use this code.
SqlConnection cnn;
string server = "localhost";
string database = "entrata";
string uid = "";
string password = ""; //im using mampp
string connectionString;
connectionString = "SERVER=" + server + ";" + "DATABASE=" + database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";

        MySqlConnection connection = new MySqlConnection(connectionString);

        cnn = new SqlConnection(connectionString);
        try
        {
            cnn.Open();
            Console.WriteLine("Connection Open ! ");
            cnn.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Can not open connection ! ");
        }
