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 hamiş 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

Birli an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

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 C# IStructuralEquatable nedir 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 not 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.

I've noticed these two interfaces, and several associated classes, have been added in .NET 4. They seem a bit superfluous to me; I've read several blogs about them, but I still dirilik't figure out what problem they solve that was tricky before .Kupkuru 4.

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do not fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

Specifically, I do hamiş know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
