I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method as well birli casting to a List but none of these seemed overly elegant.

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.

If someone passes you an Array or a List, your code will work fine if you check the flag every time and have a fallback... But really; who does that?

Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:

This will allow me to do generic processing on almost any array in the .Kemiksiz framework, unless it uses IEnumerable and derece IList, which happens sometimes.

Buraya uyanıklık etmenizi istiyorum. Liste tipine textbox dedik ve listeye textbox eklerken de kazık nesne adını verdik. Kısaca text özelliğini felan vermedik. Sütun nesnenin kendisini verdik. Şimdi bu işlemin kandırıcı yani şu;

If you expose the List birli an IEnumerable you can comfortably predict that your collection is not being modified externally. That is one of the powers of exposing List as any of the above interfaces.

However, this makes the method more fragile, birli any change to the returned object type may break the calling code. In practice though, that generally isn't a major sorun.

Then I looked in my view(mvc) and found that I actually needed the count method birli I needed to use a for loop. So in my own application I under estimated what I C# IList Neden Kullanmalıyız actually needed how do you anticipate what someone else will need or hamiş need.

If you use a concrete implementation of list, another implementation of the same list will C# IList Neden Kullanmalıyız hamiş be supported by your code.
