Objektorientiertes C#

Classes and Objects

A class defines a reusable reference type; each object has its own state.

How it works

Model state and behavior together in a C# class.

The constructor establishes valid initial state and the method changes state through a controlled operation.

Runnable C# example

Program.cs

using System;

class Counter
{
    public int Value { get; private set; }
    public void Increment() => Value++;
}

class Program
{
    static void Main()
    {
        var counter = new Counter();
        counter.Increment();
        counter.Increment();
        Console.WriteLine(counter.Value);
    }
}

Expected output

Practice with the debugger

Set a breakpoint on an important assignment or condition, click Debug, and inspect the local values before stepping to the next line.
