What are nested classes in C#?
A nested class is a class declared in another enclosing class. It is a member of its enclosing class and the members of an enclosing class have no access to members of a nested class.
Let us see an example code snippet of nested classes in C# −
class One { public int num1; public class Two { public int num2; } } class Demo { static void Main() { One a = new One(); a.num1++; One.Two ab = new One.Two(); ab.num2++; } }
The example shows that class Two is a nested class. Class Two is enclosed inside the class One declaration.
The class Two here is enclosed inside the declaration of class One. Class Two is thus a nested class. Because it has a public accessibility modifier, it can be accessed in places other than class One's scope.
