A singleton class is only one instance of the class can generated through out the Application. So multiple user can access the Singleton object.
can you provide sample code.

What I have tried:

A singleton class is only one instance of the class can generated through out the Application. So multiple user can access the Singleton object.

C#

    public class loggerclasses
    {

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

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

                return instances;
            }

        }
}

How to proceed further.

If I understand based on the title of the question, you want a singleton class which can be inherited by other class. Quick solution is to mark the default constructor with the scope - protected, instead of private. In this way, the class is still singleton, but any other class inheriting this class cannot be a singleton.

Further, what you have tried is absolutely correct, except that it needs additional thread safe code as and where required.
