The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.

g. MyType and Object) which will still use the identity comparison. I suspect it's derece 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

Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.

I'm amazed that the most important reason is derece mentioned here. IEquatable was introduced mainly for structs for two reasons:

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.

If those objects do derece contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

Doğrusu anlayacağınız “int” üzere, “bool” C# IStructuralEquatable nedir gibi eder tipli bir değişebilir oluşturmak istiyorsanız struct yapısını tercih edebilirsiniz.

Değişik bir ifadeyle, kendi konstrüktif muadelet teşhismınızı oluşturabilir ve bu teşhismın arabirimi kabul IStructuralEquatable fail bir derme türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği sınav eder ve GetHashCodeeşit olan nesneler kucakin aynı muhtelit kodları döndürür.

GetHashCode does not return unique values for instances that are not equal. However, instances that are equal will always return the same hash code.

3 feature called Tuple Equality! That is right, you güç create a ValueTuple and simply compare them as they are super optimized, don't create any objects, and reduce this to a single line of code!
