A static member belongs to the class rather than to the instances of the class. In C# data fields, member functions, properties and events can be declared static. When any instances of the class are created, they cannot be used to access the static member.
To access a static class member, use the name of the class instead of an instance variable
Static methods and Static properties can only access static fields and static events.
Like: int i = Car.GetWheels;
Here Car is class name and GetWheels is static property.
Static members are often used to represent data or calculations that do not change in response to object state.
