What would be the NEXT best playlist to watch after finishing "C# for Beginners"? I definitely learned a lot from those two awesome instructors.

Easier way to understand OOP than what I was taught.

How to implement this primary constructor in a derived class if its base class has a constructor parameters? I tried this code but it doesn't work: public class Animal(string name, int age) { public string Name { get; } = name; public int Age { get; } = age; } public class Dog(string name, int age, string breed) : base(name, age) { public string Breed { get; } = breed; } Edit (this is now the new way): public class Animal(string name, int age) { public string Name { get; } = name; public int Age { get; } = age; } public class Dog(string name, int age, string breed) : Animal(name, age) { public string Breed { get; } = breed; } thanks this is great!

What’s the difference between public string First { get; } = firstname; public string First => firstname; public string First { get => firstname; } I know the result might be the same but I can’t see the difference 😢

@VivekGawande1 5 месяцев назад

The first one sets a default value for the First property. The second one is a computed property, so it won't be stored in the object, it's calculated whenever we read the property. The last one I guess is similar to the first one

Looks like copy of the Kotlin language syntax. 🙂 Java + Kotlin = C#

@antosha2224 7 месяцев назад

No its Kotlin is copy of C#. C# was created in 2001 and Kotlin was created only in 2016 after 15 years of C# exising

@maneshwar3468 7 месяцев назад

@@antosha2224 Nope. C# introduced many new features in version 12, those features ex, primary constructor, look similar to Kotlin Lang.

@antosha2224 6 месяцев назад

@@maneshwar3468 So what? Originaly Kotlin was inpired by C# and other languages. Some features was copied directly from C# . Here is the text from their oficial documentation in kotlin org / introduction : "Kotlin took inspiration from many programming languages, including (but not limited to) Java, Scala, C# and Groovy. ". You can go to Kotlin docs intrudaction and read this by yourself. So creator of Kotlin by himself says that Kotlin was inpired by C# and you says "NOPE" lol
