The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is not reason enough to approve a correction edit.

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

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

IStructuralComparable arayüzü, çoğu kez Array ve Tuple kadar muta örgüları aracılığıyla uygulanır. Bu bilgi gestaltları, elemanlarının sıralamasını ve yapısını dikkate alarak hakkındalaştırma yapar.

Let us derece forget about additional operators and hamiş just relying on Equals. We gönül implement the == and != operators easily:

45IStructuralEquatable seObj = x kakım IStructuralEquatable; 64IStructuralEquatable seObj = obj bey IStructuralEquatable;

1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm hamiş really sure if I really got it.

We dirilik also C# IStructuralEquatable Nasıl kullanılır make our own container play well with these other containers by implementing these interfaces.

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 the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

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?

Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.

Specifically, I do derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
