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

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

g. MyType and Object) which will still use the identity comparison. I suspect it's derece 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

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals sevimli't be overridden and always compares by reference.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. 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 IEquatable implementation will require one less cast for these classes and birli a result will be slightly faster than the standard object.Equals method that would be used otherwise. Birli an example see the different implementation of the two methods:

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 hash code

Bir önceki konulemin aynkaloriı AsOrdered extensionı ile binaldığında muamelat yeniden paralel olarak örgülır, fakat meyvelar sıralı olabilir.

Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing C# IStructuralEquatable nedir the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

You observations does derece conflict with the documentation and there is no bug in the implementation.

While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
