  • C# or C-Sharp is the programming language behind .NET (dotnet) and the Unity framework. It was created at Microsoft as a C-like object-oriented language and is used to build apps for web, desktop, mobile, and more.

      I feel like this is actually the most important part of a language for me. Like C++ isn't a bad language, but the documentation and tooling around it just makes me hate working with it. I'm not a big fan of C# (more of a Rust guy), but having nice documentation and tooling just elevates the experience so much. Honestly, I feel like it's a sin when a language doesn't prioritize that stuff.

    LINQ was my introduction to functional programming many years ago. At the time, I didn't know it was functional programming. I just knew it was very different and very cool.

    •  2 ปีที่แล้ว +2

      LINQ is what I miss the most when working with Java and even Python. The fluent syntax is just so good to use.
      I personally dislike the global-style of the functional part of Python. I'd rather do a list comprehension for filtering/mapping than using map and filter. What I do miss from Python, though, is list, tuples, sets and dicts being built-in, which cleans up the syntax quite a lot.

    • @mctechcraft7
      @mctechcraft7 2 ปีที่แล้ว +7

      LINQ is honestly the most OP feature of C# in my opinion. You can get so much done with just a few chained method calls. Even better you can add your own extension methods to make custom LINQ methods

    • @mctechcraft7

      @ lists and dicts are part of System.Collections.Generic namespace. I think that is auto imported if you enable implicit using sus but id have to check

    •  2 ปีที่แล้ว

      @@mctechcraft7 extension methods are a close second indeed. About Sytem.Collections.Generic what I meant is having these data structures literally part of the syntax. Auto-importing it everywhere is cool, but still not as "transparent" as it is in Python. Out of the basic data structures, Tuple is the closest right now to feeling like part of the language (not the library), although having to access members as Item1, Item2, Item3... is still ugly IMO.

    • @janne_kekalainen
      @janne_kekalainen 2 ปีที่แล้ว

      @ For tuples in a method return type, you can do the following:
      public (int X, int Y) Do something(int a, int b){
      // Do something useful
      return (a*2,b*3)
      }
      var thing=DoSomething(1,2)
      // Since the elements were named before, we can do.
      Console.WriteLine(thing.X+thing.Y)
      // or alternatively if you want x and y as separate variables.
      (var x, var y) =Do something(1,2)
      //---
      I absolutely love tuples; they solve the annoying issue of returning multiple values from a method. Sure there was a way before with an out parameter, but tuple is a cleaner solution, in my opinion.

    Destructors, aka. finalizers, should only be used in C# when absolutely necessary, as they introduce a significant amount of overhead.

    Some comments based on the C# code seen in the vid:
    1. While you can write finalizers/destructors for types in C#, it's not very common and not very useful. Due to how garbage collection works, you can't ever count on a finalizer being called. If you need to do something to deallocate special resources (like a file handle or a database connection) you'd implement the IDisposable interface on the class instead.
    2. When writing asynchronous code, try to avoid writing 'async void' functions as much as possible! Async void will break the exception-handling system of .NET. Instead, declare async methods as returning Task. (e.g. 'public async Task MyCoolAsyncMethod()')

    1:22 Nowadays most C# programmers would write `var hello = "string";` (equivalent of `let` in Typescript)
    1:32 It would have been nice to use C# 10 syntax for namespaces (e.g. no brackets).
    1:39 Finalizers are not invoked when objects go out of scope. The closest thing to scope-based resource management is `using`/IDisposable. Finalizers are invoked non-deterministically once an object is eligible for garbage collection (which is only tangentially related with scope). It's unfortunate that they used syntax resembling C++ destructors, because this has been a common misconception ever since.
    1:52 C# does have top-level functions, albeit for the specific use case of small programs that are held in a single file.

      Why on Earth would people intentionally use var? I do not understand this. One of the biggest advantages of C sharp is that it’s statically typed. Like how typescript is an upgrade from JavaScript because it’s statically typed. Using “var” instead of the actual type is just lazy and makes it significantly harder and more frustrating for your teammates to read your code later (as well as your future self). Am I missing something?? Using the actual types makes it way easier to understand what you are doing in the first place

    Reference types can still be null even with the nullable reference type feature enabled, but you get warnings in most scenarios
    it's not a destructor but a finalizer, and you have no way of knowing when or even if it gets called at all, since it is called when the garbage collector decides it want's to get rid of that object after it is no longer in use. The closest thing to a destructor is Dispose in combination with using which you get through the IDisposable interface.
    Also, when you use async/await you almost always want to have Task or variations thereof as your return type and not void :)

      If it were called "Finalizer" then that makese the term 'finally' in try catch to not make sense, because finally in try catch is a 'finalizer' ergo code that runs regardless of the end result (except for Exceptions). A destructor does not match that behavior, so the term "finalizer" doesn't make sense.
