Strategy Design Pattern Explained Using C#

Показать описание

This episode explains the strategy design pattern and how to use it in a real world application. The strategy design pattern is a behavioral pattern that allows for an interchangeable execution path at runtime.

The strategy pattern is useful for situations where it is necessary to dynamically swap the algorithms used in an application. The strategy pattern is intended to provide a means to define a family of algorithms, encapsulate each one as an object, and make them interchangeable.

In software engineering, a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. A design pattern is not a finished design that can be transformed directly into source or machine code.

Thanks for your great explanation. This is a great start point for learning the Strategy pattern but it would be great if you could also explain how you would set a strategy object in a more elegant way (as you mentioned). Because after all, this pattern is used to replace the Switch statement with Polymorphism, but you're still using Switch.

Wow... A little over than a minute is what took you to explain this concept in a way I can understand. Seriously I watched a 35 min video including code and everything and still had no clue what the hell is going on. This was clear and to the point. Thank you.

I've been watching a lot of theoretical videos on this pattern. This pragmatic video is the most clear to me. Seeing how you inject specific methods into the general interface was exactly what I have been trying to find! Thank you so much!

Switch makes it ugly, save it as a property to a context object and pass it through a constructor and/or setter method. With switch youre not really decoupling bc you have to add the new case each time.

One of the usages of the strategy pattern is getting rid of Switch/Case statement... not a good idea to use that to explain "strategy pattern"!

Hey, what other more elegant ways of selecting a strategy be?

Thank you for your great video tutorial, please tell me what theme are you using the in the Visual Studio? very beautiful theme.

Fantastic explanation! Now I can go back to my PluralSight course and know what that guy was talking about.

Thank you. Very clear and helpful. I've not yet found a design pattern book (I have four) or video that clearly explains design patterns. They always feel the need to add a lot of code to their examples that only confuses me. Often it's hard to know what part of the code is the pattern 🤥. Maybe you might consider doing a video on each of the patterns.
