Flag ile kullanımda çabucak bir tomar enum kıymeti kullanarak farklı kombinasyon kıymeti ile bir çok ulaşılabilecek tanım kümesi tanılamamlanabilir.

I particularly feel that the GetHashCode() could do with some improvement, because it doesn't give unique values for objects with different reference objects nested further.

I have a list of custom object where I am trying to remove duplicate records. I am seeing so many online articles which points towards IEqualityComparer(I've never used this before). Question is, when should I use it? I güç achieve same result by LINQ in one line code.

There are many cases where one might want to have a Dictionary locate objects using something other than 100% equivalence. Kakım a simple example, one may wish to have a C# IEqualityComparer nerelerde kullanılıyor dictionary which matches in case-insensitive fashion. One way to accomplish that would be to convert strings to a canonical uppercase form before storing them in the dictionary or performing a lookup. An alternative approach is to supply the dictionary with an C# IEqualityComparer Nasıl Kullanılır IEqualityComparer which will compute hash-codes and check for equality in some sort of case-independent function. There are some circumstances where converting strings to C# IEqualityComparer nedir canonical form and using that form whenever possible will be more efficient, but there are others where it's more efficient to only store the string in its original form.

This interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the IComparer interface.

When we make the inference from allPositions to IEnumerable we say "IEnumerable is covariant in T, so we kişi accept Position or any larger type

According to this thinking, both types should implement IEquatable, because it doesn't seem likely that there are other meaningful ways C# IEqualityComparer Kullanımı of doing an equality test.

The same goes for the LINQ operators that accept a comparer. But again, always consider if the equatable behavior that should be intrinsic to the class rather than defined externally.

Doing that you changed the behavior for a single class, what if you need the same logic for other classes? If you need a C# IEqualityComparer Nasıl Kullanılır "generic comparison". That is why you have IEqualityComparer.
