Protecting a class in a namespace

Question

In the namespace, I have a utility class that only works with the main class that I am viewing. How can I hide this?

Answer 1

Make your class internal and work with different assemblies or create a private nested class of your main class.

public class A
{
  private class B { ... }
  ...
}

Answer 2

If it will be used only internally - inside this "main class" - then it would be most suitable for its nesting.

In other words, your structure will look like this:

public class MainClass
{
    // ...

    private class NestedUtilityClass
    {
        // ... 
    }
}
