It is not possible to make reference to a static variable from a non-static method. To understand this, you need to understand the difference between static and non-static.

Static variables are referred to as the  class variables, they belong to the class with their only one instance, created at the first only. Non-static variables are initialized every time you create an object of the class.

Now, coming to your question, when you use new() operator we will create a copy of every non-static field for every object, but it is not the case for static fields. That's why it gives a compile time error if you are referencing a static variable from a non-static method.
