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.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Safi Core 2.1 application there is an even cooler way of doing this:

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code birli well. The next logical step would be to just use .Equals on the entire metrics.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural C# IStructuralEquatable nedir hash code

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

This member is an explicit interface member implementation. It yaşama be used only when the Array instance is cast to an IStructuralEquatable interface.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

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.
