However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kupkuru Core 2.1 application there is an even cooler way of doing this:

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

In this equating the values in arrays may be same or different but their object references are equal.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to not trigger new events unless a value changed a whole new world opened up to me.

IStructuralEquatable is quite new and unknown, but I read somewhere that it can be used to compare the contents of collections and arrays. Am I wrong, or C# IStructuralEquatable nedir is my .Net wrong?

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

To achieve this, employee objects with matching SSN properties would be treated kakım logically equal, even if they were derece structurally equal. Share Improve this answer Follow

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 hayat just compare each of them":

Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.

While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
