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

Bu sayede, data strüktürlarının bağırsakindeki verilerin sıralanması veya kontralaştırılması hizmetlemleri özelleştirilebilir ve muayene edilebilir hale hasılat.

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

Important Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

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.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

The IEquatable implementation will require one less cast for these classes and bey a result will be slightly faster than the standard object.Equals method that would be used otherwise. C# IStructuralEquatable Kullanımı Birli an example see the different implementation of the two methods:

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

Projeyi yayınladıgınız dönem user secrets kullanılmıyor. Bu yalnızca ihya aşamasında kullanılabilir.

Yapısal muadelet, bedel değerlere mevla oldukları karınin iki nesnenin tay evetğu demeına gelir. Aynı fiziksel nesneye servurdıkları muhtevain dü nesne mebdevurusunun bedel bulunduğunu gösteren referans eşitliğinden farklıdır. arabirimi, IStructuralEquatable derme nesnelerinin konstrüktif eşitliğini denetlemek derunin özelleştirilmiş mukabillaştırmalar uygulamanıza imkân teşhisr.

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.

Bu kuruluşya denli oluşturduğumuz bütün nesnelerin Heap kısmında olduğunu söylemiştik. Halbuki Stack kısmında struct kuruluşsında nesneleri tutabilmekteyiz.

Here the comparison is different for value type arrays and custom arrays. In .Safi 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
