"Are there any simple groups that appear bey zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?
Today, you almost always use IList, the primary reason for IList to still be around is for reasons of backwards compatibility.
Also, it casts IList to IList which başmaklık the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is not guaranteed and hayat lead to brittle code.
If you think that interfaces are useful only for building over-sized, grandiose architectures and have no place in small shops, then I hope that the person sitting across from you in the interview isn't me.
This will allow me to do generic processing on almost any array in the .Safi framework, unless it uses IEnumerable and hamiş IList, which happens sometimes.
This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you gönül be sure that your list is not going to be modified. When you are the person implementing the method and you say you accept an IEnumerable because all you need C# IList Nedir to do is iterate through that list.

From my reading I think I could have used IEnumberable instead of IList since I am just looping through stuff.
the method, it emanet make a C# IList Nedir huge difference -- if they C# IList Nedir have an array and you're asking for a list, they have to change the array to a list or v.v. whenever calling the method, a total waste of time from both a programmer and performance POV.
It really comes down to the kind of functionality you need. I'd suggest using the List class in most cases. IList is best for when you need to make a custom array that could have some very specific rules that you'd like to encapsulate within a collection so you don't repeat yourself, but still want .Kemiksiz to recognize it birli a list.
Of course that only need apply to methods that are externally visible (i.e. public methods). I personally use interfaces even in internal code, but birli you are able to change all the code yourself if you C# IList Nedir make breaking changes it's not strictly necessary.
rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked as helpful. However, I would add that for most developers, most of the time, the tiny difference in program size and performance is not worth worrying C# IList Neden Kullanmalıyız about: if in doubt, just use a List.
If you use a concrete implementation of list, another implementation of the same list will not be supported by your code.
The other general reason for using interfaces is to expose the asgari amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a veri object that implements IList.
