Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.

Bu tür bir alınlaştırma, makale esaslıklarının sıralamasının önemli başüstüneğu durumlarda, yapısal benzerliklerin veya değişiklıkların belirlenmesine yardımcı kabil.

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

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

It is used by the third example kakım 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.

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may hamiş give you the correct results in this super simple example:

Bir önceki işlemlemin aynısını AsOrdered extensionı ile mimarildığında iş gene paralel olarak bünyelır, ancak payanlar sıralı olur.

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.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

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.
