If equality is hamiş needed for the derived class you sevimli skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

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.
After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.
We birey also make our own container play well with these other containers by implementing these interfaces.

Each of your objects should use a hashcode C# IStructuralEquatable Nasıl kullanılır based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.
You observations does hamiş conflict with the documentation and there is no bug in the implementation.
Specifically, I do derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
