How can we call the base class method without creating an instance?

For Static Methods ,You can call a base class method without creating an instance of the class by using static methods Example :- BaseClass.StaticMethod(); For Non-Static Methods: For non-static methods, you must create an instance of the derived class or use an existing instance of the base class if it is accessible. Example : BaseClass instance = new DerivedClass(); instance.BaseMethod(); In summary , non-static base class methods require an instance, whereas static methods can be called directly on the class itself.

I believe by using :base

In many programming languages, including C#, you can't directly call a base class method without creating an instance of the derived class. The base class method belongs to a specific instance of the class, and you need that instance to invoke its methods. However, if you're trying to access a static method of the base class (a method marked with the static keyword), you can call it using the base class name directly, without needing an instance of the class.
