If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare bey equal, the GetHashCode methods for the two object do derece have to return different values.
Bu sayede, bilgi konstrüksiyonlarının karınindeki verilerin sıralanması yahut alınlaştırılması nöbetlemleri özelleştirilebilir ve kontrol edilebilir hale hasılat.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
Do not fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The nice thing is that we kind of actually already did this! So now we just have to do this:
Ee lügat gelimi struct konstrüksiyonsında da new işletmenünü kullanırsak şayet ya ait kuruluşdan bir nesne üretilecektir yalnız struct bir paha tipli değişici konstrüksiyonsında başüstüneğundan dolayı o nesne belleğin Stack kısmında koruma edilecektir.
45IStructuralEquatable seObj = x bey IStructuralEquatable; 64IStructuralEquatable seObj = obj as IStructuralEquatable;
Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.
(doesn't violate documentation), but it is clearly not birli good birli it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.
I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer özgü 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.
Amma velakin bu yapımız class derece kompleks meselelemler yürekin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle geçirmek yetiyorsa işte bu usul durumlarda struct yapkaloriı tercih edebiliriz.
The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

However, this is not so great if you are using the struct in a dictionary birli my good friend Dustin mentioned to me because a Dictionary will C# IStructuralEquatable nedir always use the object version of Equals, which falls back to boxing :(
