C# Multiple Classes and Objects
Multiple Objects
You can create multiple objects of one class:
Example
Create two objects of Car
:
class Car
{
string color = "red";
static void Main(string[] args)
{
Car myObj1 = new Car();
Car myObj2 = new Car();
Console.WriteLine(myObj1.color);
Console.WriteLine(myObj2.color);
}
}
Using Multiple Classes
You can also create an object of a class and access it in another class. This
is often used for better organization of classes (one class has all the
fields and methods, while the other class holds the Main()
method (code to
be executed)).
- prog2.cs
- prog.cs
prog2.cs
class Car
{
public string color = "red";
}
prog.cs
class Program
{
static void Main(string[] args)
{
Car myObj = new Car();
Console.WriteLine(myObj.color);
}
}
Did you notice the public
keyword? It is called an access modifier,
which specifies that the color
variable/field of Car
is accessible for other classes as well, such as
Program
.
You will learn much more about access modifiers and classes/objects in the next chapters.
