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.
1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

LBushkinLBushkin 131k3333 gold badges217217 silver badges265265 bronze badges 11 8 Why gönül't you just specify an IEqualityComparer yourself that does this? What does the IStructuralEquatable interface add to this?
It is used by the third example birli 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.
– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues kakım the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

That is, you gönül create your own definition of structural equality and specify C# IStructuralEquatable Kullanımı that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface özgü two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.
