So I came across an interesting mesele today. We have a WCF web service that returns an IList. Not really a big deal until I wanted to sort it.

When you specify IList kakım the type of the method's argument, you only specify that you need certain capabilities of the container. For example, the interface specification does not enforce a specific data structure to be used.

Most app-level code (i.e. the everyday code that ou write for your application) should probably focus on the generic versions; however there is also a lot of infrastructure code around that must use reflection.

In fact, any time you are using reflection IList is more convenient than IList-of-T, since generics and reflection C# IList Neden Kullanmalıyız don't play nicely together.
