Am confused by Namespaces

I am confused by the explanation of Namespaces. It is said that System.Console.Write(); is Namespace.ClassName.MethodName(parameterType parameterName); but if the namespace is i.e. Treehouse, wouldn't it be Treehouse.Console.Write();?

Hi Chase,

It can be confusing to grasp the concept of namespaces, but I assure you they are quite simple :smile:. As the example given by Jeremy is System.Console.Write, the namespace for Write will always remain as System since that is where the Console class is encapsulated within.

The namespace Treehouse, which we use to encapsulate the Program class only affects Program. All external classes are unaffected by our namespace of Treehouse as they weren't defined within it. If we wanted our own Console class with our own Write method, we would have to declare all of that code ourselves which wouldn't serve much of a purpose since we would be writing duplicate code.

To recap:

  • System is a pre-defined namespace set by .NET
  • Treehouse is a custom namespace that was defined by us

Hope that helps.
