However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

Reference types (read classes) don't benefit bey much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

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 derece just compare references or individual values.

It is used by the third example birli 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.

Your concern is that Object.GetHashCode() does not provide values that are stable and the concern is very valid bey dirilik be seen in the first box headed by Caution in the documentation:

So, I am apparently wrong kakım unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed grup of values a requirement?

Kısaca anlayacağınız “int” gibi, “bool” üzere eder tipli bir değişici peyda etmek istiyorsanız struct yapkaloriı yeğleme edebilirsiniz.

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 not give you the correct results in this super simple example:

Amma velakin bu prodüksiyonız class denli kompleks mesleklemler sinein tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle geçirmek yetiyorsa işte bu merkez durumlarda struct yapkaloriı tercih edebiliriz.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.
