Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

In certain scenarios (such as using the value type kakım a key in a dictionary) it birey murder performance in one foul swoop.

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

– 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.

What does IEquatable buy you, exactly? The only reason I emanet see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

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:

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.

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

GetHashCode does hamiş return unique values for instances that are not equal. However, instances that are equal will always return the same hash code.
