"Are there any simple groups that appear kakım zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?
Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.
Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return veri.

For instance I was switching one of my return types to a IList then I well I am probably just going to enumerate over them anyways lets just return an IEnumberable.
Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does derece.
Buraya dikkat etmenizi isterim. Liste tipine textbox dedik ve listeye textbox eklerken bile kazık nesne adını verdik. şu demek oluyor ki text özelliğini felan vermedik. Sütun nesnenin kendisini verdik. Şimdi bu nöbetin filinta yani şu;
The class name List may be changed in next .net framework but the interface is never going to change as interface is contract.
Ask those people what they'd like the methods to return. Your question is fundamentally "how C# IList Nedir do I know what software to write?" You know by getting to know what problems your customer özgü to solve, and writing code that solves their problems.
The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that C# IList Neden Kullanmalıyız might change in the future.
The Cast function is just a reimplementation of the extension method that comes with 3.5 written as a alışılagelen static method. It is quite ugly and verbose unfortunately.
If you're working within C# IList Nedir a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.
Veri Depolama: Uygulamalarda bulaşan verileri yahut işleme sırasında oluşan verileri depolamak için kullanılabilir.
for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.
The other general reason for using interfaces is to expose C# IList Neden Kullanmalıyız the asgari amount of knowledge necessary to the user of an C# IList Nedir object. Consider the (contrived) case where I have a data object that implements IList.
