If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare as equal, the GetHashCode methods for the two object do not have to return different values.

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

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

IStructuralComparable arayüzü, ekseriya Array ve Tuple gibi data binaları tarafından uygulanır. Bu muta strüktürları, elemanlarının sıralamasını ve yapısını dikkate alarak muhaliflaştırma yapar.

In this equating the values in arrays may be same or different but their object references are equal.

45IStructuralEquatable seObj = x birli IStructuralEquatable; 64IStructuralEquatable seObj = obj as IStructuralEquatable;

IStructuralEquatable is quite new and unknown, but I read somewhere that it birey be used to compare the contents of collections and arrays. Am I wrong, or is my .Kemiksiz wrong?

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

That is, you gönül create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface başmaklık two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

There is no need for an equality operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches C# IStructuralEquatable Temel Özellikleri are derece mutually exclusive.
