That method must return a MySqlConnection object.
Probably

return con;

just before the closing curly bracket will do the trick.
:rolleyes:

the problem is, that you are not returning a MySqlConnection. What you could do is:

C#

public static MySqlConnection m_con;

public static MySqlConnection GetConnection(string server, string user, string password, string db)
{
    string str = "Server='" + server + "';user='" + user + "';password='" + password + "';database='" + db + "';";
    m_con = new MySqlConnection(str);
    con.Open();
    isConnected = true;
    return m_con;
}

Solution 1

You need to return an object of type MySqlConnection. In this case that would be con.
