Methods and objects

Methods belong to classes. The released compiler supports static methods, instance methods, constructors, instance fields, parameters, return values, and recursion.

namespace Counters {
    public class Counter {
        private int value;

        public Counter(int initial) { value = initial; }

        public int Add(int amount) {
            value = value + amount;
            return value;
        }
    }

    public class Program {
        public static int Double(int value) { return value * 2; }

        public static int Main() {
            Counter counter = new Counter(10);
            System.Console.WriteLine(counter.Add(Double(3)));
            return 0;
        }
    }
}

new Counter(10) allocates a managed reference object and invokes its constructor. Field initializers run before the constructor body. A class without a declared constructor has a parameterless default constructor. Fields start at zero, false, or null when not initialized.

Class assignment copies a reference, not an object. this refers to the current instance. Static methods have no this; pass an object explicitly to access its instance members.

The current release does not support overloads, inheritance, interfaces, structs, generic methods, or static fields.
