What does it mean to inject and also create one class from another (MVP pattern) in C#?

Question

OOP

Hello!
There is a scheme for the interaction of classes with each other according to the MVP (Model-View-Presenter) principle. (1) One interaction is described as follows: The Presenter injects (Databases added in brackets) Services. (2) Or another interaction: Presenter creates (in brackets CurrentRecord) Model.
I know that (1) implies Dependency Injection, but I don't understand how it should work here, because. I haven't had to deal with DI yet.
And according to (2), the question is also: does this mean that it is necessary to create objects of the View type in the Presenter class?
Thanks for any insights.

Answer 1

1. Injects, which means it does not create an instance within itself (i.e. does not make new Service()), but takes Service as a parameter, most often as a constructor parameter

var service = new Service();
var presenter = new Presenter(service);

2. Yes, this means that the presenter must create a model internally and return it for display. And the text does not say that this is a view. These are two different models.

Answer 2

eRK Thank you. (2) Yes, I'm sorry, I meant Model, not View, a typo. And what can mean CurrentRecord in brackets? This is some kind of current model. How would this look like in code?
Here, for example, it stands: from View (this is no longer a typo :)) a single instance is created through the DI Container. What is a DI Container ?, is it when "something" is passed through a parameter?
(1) And here, probably in brackets, we mean the Service for communicating with the Database. Those. The Presenter takes the Service as a constructor parameter, thereby dynamically communicating with it, and through the Service there is a dialogue with the database, perhaps so?
