Answer 1

Singleton means that the class that you have made can be instantiated only once. So if you want that to happen, do two things:

1. Make the constructor private.(This is to prevent other classes from accessing it.)

2. instantiate the class as:

   get
   {
    if(instance == null) //important coz, the class will be instantiated only on the first call
    {
      instance = new singletonDb;
    }
    return instance;
   }
