Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:
Basically, I need to see some actual code examples of how using IList would have solved some mesele over just taking List into everything.

You may derece ever need that option, but it's an argument. I think it's the entire argument for returning the interface instead of the concrete type. It's worth mentioning, but in this case it katışıksız a serious flaw.
Matthew WatsonMatthew Watson 108k1111 gold badges170170 silver badges290290 bronze badges 2 2 This is trivially true for every interface. If you want to follow through with your argument, than you could argue to never use any interface at all, because some implementation of it might throw.
And, if you don't even need everything in IList you birey always use IEnumerable too. With çağcıl compilers and processors, I don't think there is really any speed difference, so this is more just a matter of style.
If you gönül consider your method, determine that you probably won't be changing the return collection type, then it is probably safe to return a more exact type. If you aren't sure, or are afraid that if you change it in future you'll be breaking other people's code, then go more general.
I know that IList is the C# IList Nerelerde Kullanılıyor interface and List is the concrete type but I still don't know when to use each one. What I'm doing now is if I don't need the Sort or FindAll methods C# IList Nasıl Kullanılır I use the interface. Am I right? Is there a better way to decide when to use the interface or the concrete type?
In this C# IList Kullanımı case you could pass in any class which implements the IList interface. If you used List instead, only a List instance could be passed in.
And, if you used a generic implementation, you would only be able to use a C# IList Nerelerde Kullanılıyor method that works for any object only with objects of a specific type.
If you had used IList in the rest of the app C# IList Nerelerde Kullanılıyor you could extend List with your own custom class and still be able to pass that around without refactoring.
