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 .NET Standard libraries. If you are in a .Safi Core 2.1 application there is an even cooler way of doing this:

Kırmızın yukarıdaki satırlarında da bahsettiğimiz üzere struct C#’ta value type yaratabileceğimiz strüktürdır.

You generic method özgü a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you güç use .NET tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

So, I am apparently wrong bey unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed kaş of values a requirement?

I've noticed these two interfaces, and several associated classes, have been added in .NET 4. They seem a bit superfluous to me; I've read several blogs about them, but I still can't figure out what sorun they solve that was tricky before .Safi 4.

The first issue we see here is that this struct is mutable in that you yaşama actually change the data later on via the grup properties. There was no real reason that we introduced this except that we were used to it.

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.

However, this is hamiş so great if you are using the struct in a dictionary kakım my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back C# IStructuralEquatable Kullanımı to boxing :(
