It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
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.
g. MyType and Object) which will still use the identity comparison. I suspect it's derece a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and
Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals sevimli't be overridden and always compares by reference.
Let us derece forget about additional operators and derece just relying on Equals. We emanet implement the == and != operators easily:
comparer IEqualityComparer An object that determines whether the current instance and other are equal.
What does IEquatable buy you, exactly? The only reason I emanet see it being useful is when creating a generic type and C# IStructuralEquatable Kullanımı forcing users to implement and write a good equals method.
şu demek oluyor ki anlayacağınız “int” üzere, “bool” üzere bedel tipli bir kararsız peydahlamak istiyorsanız struct yapısını yeğleme edebilirsiniz.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.
Bu yapıya kadar oluşturduğumuz bütün nesnelerin Heap kısmında bulunduğunu söylemiştik. Oysa Stack kısmında struct dokumasında nesneleri tutabilmekteyiz.

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
