OOPS concepts in c#

[Lost User]

Take a look at the Singleton pattern[^].

One of these days I'm going to think of a really clever signature.

What does this have to do with OOPS concepts? What you are describing is such a basic request that it's part of the framework; we call them "static classes".

public static class MySingleObjectClass
{
public static void PerformSomeAction()
{
}
}

If we create static class , we cannot able to create instance. but ,my query is that instance should be created only one time and restrict to more than one.

If you want to restrict the class so that it can only be seen by one particular external assembly, you use internal to limit the scope to the current assembly, and then you implement InternalsVisibleTo[^] to link this to the specific assembly.

Are you suggesting InternalVisible to be used in the parent class? Up to my knowledge InternalVisible access modifier is not there in c#

Did you even bother opening the link in the answer?

No, because that would violate the rules of "spoon feeding".

There's one instance by definition, so no use in creating it.

That's exactly what the static class was intended for.
