Singleton class implemented in Class A and ClassB

You can not inherit a class which has only private constructor.

Have a look into my article about Singleton.

 

http://www.c-sharpcorner.com/article/singleton-design-pattern-in-c-sharp/  

namespace singletonclass
{

public class loggerclasses
{

public static loggerclasses instances = null;
private loggerclasses()
{
}

public static loggerclasses Instances
{
get
{
if (instances == null)
{
instances = new loggerclasses();
}

return instances;
}

}
}
public class A : loggerclasses
{
public void classa()
{
Console.WriteLine(" object A: is created");
}

}

class Program
{
static void Main(string[] args)
{
A obj =new A();
obj.classa();
}
}

}

 

Questions : I want to do Singleton class inheritance with class A and class B to get the output as

object A: is created

object B: is created.
