Question

My MySqlConnection class implements IDatabaseConnection interface. In update method, I want to call connect() but it cannot find this method, How can I call it?

class MySqlConnection : IDatabaseConnection
{
    void IDatabaseConnection.connect()
    {
        ...
    }

    void IDatabaseConnection.update()
    {         
        connect(); // here
        ...
    }
}

Answer 1

Apparently you’re using explicit interface implementation, except your syntax is incorrect (you mustn’t specify an access modifier on it).

To call the method, just cast this to IDatabaseConnection:

void IDatabase.update(){

    ((IDatabase)this).connect();
 ...
}
