[c#] How to form a correct MySQL connection string?

I am using C# and I am trying to connect to the MySQL database hosted by 00webhost.

I am getting error on the line connection.Open():

there is no mysql host with this parameters.

I have checked and everything seems to be fine.

string MyConString = "SERVER=mysql7.000webhost.com;" +
        "DATABASE=a455555_test;" +
        "UID=a455555_me;" +
        "PASSWORD=something;";
         MySqlConnection connection = new MySqlConnection(MyConString);
         MySqlCommand command = connection.CreateCommand();
         MySqlDataReader Reader;
         command.CommandText = "INSERT Test SET lat=" + 
             OSGconv.deciLat + ",long=" + OSGconv.deciLon;
         connection.Open();
         Reader = command.ExecuteReader();
         connection.Close();

What is wrong with this connection string?

Here is an example:

MySqlConnection con = new MySqlConnection(
    "Server=ServerName;Database=DataBaseName;UID=username;Password=password");

MySqlCommand cmd = new MySqlCommand(
    " INSERT Into Test (lat, long) VALUES ('"+OSGconv.deciLat+"','"+
    OSGconv.deciLon+"')", con);

con.Open();
cmd.ExecuteNonQuery();
con.Close();

string MyConString = "Data Source='mysql7.000webhost.com';" +
"Port=3306;" +
"Database='a455555_test';" +
"UID='a455555_me';" +
"PWD='something';";
