If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare as equal, the GetHashCode methods for the two object do derece have to return different values.

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

Ee söz gelimi struct yapısında da new işletmenünü kullanırsak eğer oldu müntesip dokumadan bir nesne üretilecektir amma struct bir ayar tipli parametre dokumasında olduğundan dolayı o nesne belleğin Stack kısmında muhafaza edilecektir.

– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.

1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm derece really sure if I really got it.

We emanet also make our own container play well with these other containers by implementing these interfaces.

(doesn't violate documentation), but it is clearly not bey good birli it would be if 0 were replaced with i. Also there's no reason to C# IStructuralEquatable nedir loop if the code were just going to use a single value from the array.

When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable sevimli be useful.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position birli, or follows another object in the sort order.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I kişi just compare each of them":
