Can I have multiple classes in one C# file?

Unlike Java, C# allows you to write multiple classes in a single source file . Note that: The “Util” class has only a single static method “Swap()”.

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#.17 Eyl 2018

In C#, it is possible to inherit fields and methods from one class to another. We group the “inheritance concept” into two categories: Derived Class (child) – the class that inherits from another class . Base Class (parent) – the class being inherited from .

A nested class is a member of its enclosing class . Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private.
