Because you need an instance and hamiş just a method call you hayat't let the generic type be inferred by the compiler (see this discussion) but have to do so when creating the instance:

Your GetHashCode implementation always returns the same value. Distinct relies on a good hash function to work efficiently because it internally builds a hash table.

Therefore, when testing two instances of T for equality, because T katışıksız no internal understanding of equality, you will have to make an explicit choice of a IEqualityComparer instance which performs the test according to your specific requirements.

Basically you could check all the properties you want to check in Equals via reflection. To filter some of them out use an attribute on those properties:

Tamam her şeyi tanımladık çok leziz töz kısma geçelim pratikte C# IEqualityComparer nerelerde kullanılıyor bunu nasıl yapacağız? Listemizi doğrusu teşhismlamıştık kalmış olduğumız yerden devam edelim.

There are many cases where one might want to have a Dictionary locate objects using something other than 100% equivalence. Kakım a simple example, C# IEqualityComparer nerelerde kullanılıyor one may wish to have a dictionary which matches in case-insensitive fashion. One way to accomplish that would C# IEqualityComparer nerelerde kullanılıyor be to convert strings to a canonical uppercase C# IEqualityComparer Nasıl Kullanılır form before storing them in the dictionary or performing a lookup. An alternative approach is to supply the dictionary with an 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 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.

Where did the pronunciation of the word "kilometer/kilometre" as "kl OM iter" rather than "KILL o meeter" originate?
