5 Basit Teknikleri için C# IStructuralEquatable Kullanımı

Wiki Article

Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.

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 not 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

Birli far kakım I see this is only exposed through the StructuralComparisons class. The only way I hayat figure out to make this useful is to make a StructuralEqualityComparer helper class kakım follow:

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code as well. The next logical step would be to just use .Equals on the entire metrics.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

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

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

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

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

Bu kuruluşya derece oluşturduğumuz tüm nesnelerin Heap kısmında olduğunu söylemiştik. Oysa Stack kısmında struct binasında nesneleri tutabilmekteyiz.

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

Specifically, I do derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
