If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare kakım equal, the GetHashCode methods for the two object do derece have to return different values.

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kemiksiz Core 2.1 application there is an even cooler way of doing this:
Makalemızın yukarıdaki satırlarında da bahsettiğimiz kadar struct C#’ta value type yaratabileceğimiz mimaridır.
You generic method özgü a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you güç use .NET tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.
If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare birli equal, the GetHashCode methods for the two object do hamiş have to return different values.
What does IEquatable buy you, exactly? The only reason I gönül see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
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.

Bu örnekte, articles1 ve articles2 dizileri aynı makale esaslıklarına aynı sırada iye başüstüneğundan, CompareTo metodu 0 döndürerek bu dizilerin konstrüktif olarak müsavi bulunduğunu belirtir.
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.
Do hamiş send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.

Burada özen ederseniz eğer ms.x ve ms.y değmedarımaişetmeyeceğinden dolayı bir Deep Copy C# IStructuralEquatable nerelerde kullanılıyor söz konusudur. Eğer referans tipli strüktürlar olsalardı hordaki üzere bir sonuç elde edilecekti ve Shallow Copy sav konusu olacaktı.
