Static members are frequently used as counters.

 

using System;

public class Starter {
    public static void Main() {
        MyClass<int> obj1 = new MyClass<int>();
        MyClass<double> obj2 = new MyClass<double>();
        MyClass<double> obj3 = new MyClass<double>();
        MyClass<int>.Count(obj1);
        MyClass<double>.Count(obj2);
    }
}

public class MyClass<T> {

    public MyClass() {
        ++counter;

    public static void Count(MyClass<T> _this) {
        Console.WriteLine("{0} : {1}",
            _this.GetType().ToString(),
            counter.ToString());
    }

    private static int counter = 0;
