Defining Classes

The syntax for defining a basic class is the following:

index


              123456
            
class nameOfClass {
    public datatype fieldName1;
    public datatype fieldName2;
    public datatype fieldName3;
    ...
}

For example, a class for storing data about houses:

index


              12345678910111213141516171819
            
using System;

class House {
    public string ownerName;
    public float landArea;
    
    public string country;
    public string state;
    public string city;
    public string streetAddress;
}

public class ConsoleApp
{
    public static void Main(string[] args)
    {
        Console.WriteLine ("Nothing here yet.");
    }
}

The above code contains a class that defines a blueprint for a 'House' object, representing a house that can store the ownerName, land area, country, state, city and street address.

Using objects is very convenient as we can group related information to form a Class and neatly create multiple instances of that data if needed. Using the House class we can easily store and access data for thousands of houses.
