It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2
It is used by the third example as 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.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation kakım an argument to the Equals method, you yaşama define a custom equality comparison for the array or collection.
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 güç also make our own container play well with these other containers by implementing these interfaces.

However, this is not so great if you are using the struct in a dictionary birli my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
