PrimeHotel – passing parameters to actions – assignments

This is a post with assignments to do if you would like to check your knowledge about ASP.NET Core in .NET 5. This one is about passing parameters to controller actions, which is a crucial thing to master when developing micro-services.

You don’t need to start from scratch, you can base on a PrimeHotel project, created especially for learning purposes. You can download it on my GitHub page. Also, take a look at the post on how to run this project: PrimeHotel – how to run this project

Assignment 1

Difficulty: easy


Learn how to write CRUD operations. Let’s say we would like to handle invoices – add all methods that will allow handling invoices.

What needs to be done

  • create a new class called Invoice
  • create Add, Get, Update and Delete methods to handle invoices
  • list of invoices can be hardcoded in the controller class
  • add optional filtering in Get with query string parameters


Have a look at the WeatherForecastController and how we handle weather forecasts there.

Assignment 2

Difficulty: medium


Learn how to pass array in a query string. It can be useful when you would like to pass a collection of objects but use a query string for it

What needs to be done

  • create a GET method
  • this method needs to accept an array of integers from the query string
  • how you would invoke this method and pass parameters?
