How to connect to a remote MySQL server using C#?

Question

I have a C# Application which would access a MySQL server using WAMP on another computer. I am trying to do it via IP. Here is my Connection String :

server = "192.168.10.221";
database = "restaurantdb";
uid = "root";
password = "";
string connectionString;
connectionString = "SERVER=" + server + "; PORT = 3306 ;" + "DATABASE=" + database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";
mycon = new MySqlConnection(connectionString);

 I have another computer in which we are in the same network, but when I try to connect to the Mysql I am not able to connect but locally it works...
What do you think ?

What I have tried:

I published my C# application and then launch it in the other computer so that I will try to connect to mysql but nothing works. But I have to mention that when I put the ip adress in the other computer I can have access to wampserver and phpmyadmin ...

I got this error: .MySql.Data.MySqlClient.MySqlException (0x80004005): Unable to connect to any of the specified MySQL hosts.
