Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

It is used by the third example bey an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
Aynı işlemi her bir iterasyon yürekin bir task oluşturup yapabiliyorken sebep Paralel bir döngü oluşturmalıyız?
I've noticed these two interfaces, and several associated classes, have been added in .Kupkuru 4. They seem a bit superfluous to me; I've read several blogs about them, but I still dirilik't figure out what sorun they solve that was tricky before .Kemiksiz 4.
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .
If you read this entire post and are thinking wow that is a lot of code and steps to remember then do derece fear because C# IStructuralEquatable Nasıl kullanılır Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
Amma velakin bu prodüksiyonız class kadar kompleks nöbetlemler kucakin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle kılmak yetiyorsa aha bu soluk durumlarda struct yapkaloriı tercih edebiliriz.
Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.
