This way, you emanet implement a test that fails if any properties are added. Of course, you'd have to add new properties to the array at the beginning. Birli using reflection is an expensive operation from a performance point of view, I'd propose to use it in the sınav, not in the comparer itself if you need to compare lots of objects.

The same return value system applies kakım IComparer. The difference between this and IComparer is IComparable will be implemented on the class that contains your field values, while IComparable derived classes are used for custom sorting. So for example:

$begingroup$ I have a custom PropertiesByValueComparer and am fairly happy how it behaves for simple classes. I haven't included comparing by fields yet. Is there anything that is blatantly işleyen about this, or do you have other recommendations?

One feature I wish .Kemiksiz had which would improve the usefulness of such dictionaries would be a means of requesting the actual key object associated with a given key (so if the dictionary contained the string "WowZo" birli a key, one could look up "wowzo" and get "WowZo"; unfortunately, the only way to retrieve an actual key object, if TValue doesn't contain a redundant reference to it, is to enumerate the entire collection).

Yeni bir paha tipi bileğaksiyonkeni oluşturulduğunda, bellekte yeni C# IEqualityComparer nedir bir meydan ayrılır ve bu saha yalnızca müteallik bileğnöbetkenin kıymetini bâtınerir.
