“this” (which is current class pointer) means current class OBJECT , so its clear that “this” only come in action once we create an Object of that class.

In case of static method, we don’t create any object of class, we call static methods without instiation that’s why this not required with static.

No, we can not used “this” keyword within a static method. because “this” keyword refers to the current instance of the class. Static Member functions do not have a this pointer (current instance). Note - we can also not used “base” keyword within a static method.

Because this points to an instance of the class, in the static method you don’t have an instance.

The “this” keyword is used as a reference to an instance. Since the static methods doesn’t have (belong to) any instance you cannot use the “this” reference within a static method.
