C# Nested Classes

CsharpProgrammingServer Side Programming

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#.

Example

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. The 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.
