That is, you dirilik create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

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.
What does IEquatable buy you, exactly? The only reason I sevimli see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.
Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison C# IStructuralEquatable nedir may derece give you the correct results in this super simple example:

That is, you güç create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface başmaklık 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.
Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.
Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are not mutually exclusive.
