In general, static means “associated with the class, not an instance”.<br /> // Search c# static review for more detail

In C#, static means something which cannot be instantiated. You cannot create an object of a static class and cannot access static members using an object. C# classes, variables, methods, properties, operators, events, and constructors can be defined as static using the static modifier keyword.

(static) >> means that the method belongs to the Program class<br /> and not an ‘object’ of the Program class.

Static classes are just tools — they don’t need specific instances and they<br /> don’t store new information.</p> <p>So you don’t have to instantiate(create an object) to access it.<br /> Static like Math.PI.</p> <p>
