将桌面c＃应用程序连接到联机mySql数据库

Question

I have a windows form application in C# and sometimes I want to push some data table from this application to an online mySql server which is hosting all data for my website in PHP. To do that I've installed :

1- MySql for visual studio version 1.2.3

2- MySql Connector.Net 6.9

Also, I have enabled Remote MySql on the server so I can make the connection. I used the '%' wildcard for the meantime because my IP address is dynamic.

my basic c# connection code is as below :

MySql.Data.MySqlClient.MySqlConnection conn;
string myConnectionString;

myConnectionString = "Server=*******;Database=*******;Uid=******;Pwd=********;";

        try
        {
            conn = new MySql.Data.MySqlClient.MySqlConnection();
            conn.ConnectionString = myConnectionString;
            conn.Open();
            MessageBox.Show("connected successfully..");
        }
        catch (MySql.Data.MySqlClient.MySqlException ex)
        {
            MessageBox.Show(ex.Message);

        }

Unfortunately, every time I run this code I am getting an error which says "Unable to connect to any of the specified MySQL hosts". I don't' know where the problem is. Is it something on the UNIX server which blocks the connections or some other thing which I need to do. I am also new to the CPanel interface and how to deal with it.

I appreciate all the help provided. Many Thanks.
