If the first item in the comparison cannot be cast to an IStructuralEquatable object (in other words, if it is not a collection object that implements the IStructuralEquatable interface), it calls the item's Equals method.
But, needless to input StructruralEqualityComparer because int is not structural, you should just use:
You are basically extracting the actual details of comparing structures to an external class that knows how to handle the particular structures being compared.

However, you do derece call the CompareTo method directly in most cases. Instead, the CompareTo method is called by sorting methods such kakım Sort(Array, IComparer). In this case, you define your IComparer implementation and pass it bey an argument to a sorting method or collection object's class constructor. The CompareTo method with your custom comparer is then called automatically whenever the collection is sorted.

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 above implementaiton causes boxing, which bey described by Microsoft is "computationally expensive". Especially since you could just compare the 4 ints that your struct consists of.
1 How do such comparators C# StructuralComparisons Kullanımı relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

ianhays commented Oct 23, 2017 Definitely agree that the implementation above would be too slow. Could we instead just write a new C# StructuralComparisons Temel Özellikleri StructuralComparer that didn't call to the nongeneric StructuralComparisons.StructuralEqualityComparer?
