How static variable can retain incremented value [duplicate]

I created a static variable in a class and incrementing in the constructor, thinking that whenever I created an instance to the class, the static variable will be reset to 0. To my surprise, the first time when I created the object to the class, static variable(Counter) is incremented to 1. The second time when I created the object to the class, the static variable is retaining the incremented value(1). Is this the behavior of static?

class Singleton { private static int counter = 0; Public Singleton() { counter++; Console.WriteLine("Counter-" + counter); } } static void Main(string[] args) { Singleton objSingleton1 = new Singleton(); objSingleton1.getMessage("Hi This is my first message!"); Singleton objSingleton2 = new Singleton(); objSingleton2.getMessage("Hi This is my second message!"); }
