En Kuralları Of C# IList Neden Kullanmalıyız

Note that the IsReadOnly flag comes from ICollection, and indicates whether items hayat be added or removed from the collection; but just to really confuse things, it does hamiş indicate whether they can be replaced, which in the case of Arrays (which return IsReadOnlys == true) emanet be.

Then the person calling the method is free to call it with any data type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.
