Basically, I need to see some actual code examples of how using IList would have solved some sıkıntı over just taking List into everything.

Convert your IList into List or some other generic collection and then you can easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)

List implements IList, and so hayat be assigned to the variable. There are also other types that also implement IList.

You emanet look at this argument from several angles including the one of a purely OO approach which says to program against an Interface derece an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you define from scratch.

additional advantage is that your code is safe from any changes to concrete class kakım you are subscribing to only few of the methods of concrete class and those are the ones that are going to be there birli long as the concrete class inherits from the interface you are using.
