This is really amazing code and works great for .Safi Standard libraries. If you are in a .Kupkuru Core 2.1 application there is an even cooler way of doing this:
IStructuralComparable arayüzü, ekseriya Array ve Tuple gibi data yapıları tarafından uygulanır. Bu bilgi örgüları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak muhaliflaştırma yapar.
Ee lakırtı gelimi struct binasında da new operatörünü kullanırsak eğer he dayalı örgüdan bir nesne üretilecektir yalnız struct bir kıymet tipli oynak örgüsında evetğundan dolayı o nesne belleğin Stack kısmında koruma edilecektir.
If two objects compare kakım equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare as equal, the GetHashCode methods for the two object do hamiş have to return different values.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
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 kellelıklarına aynı sırada malik olduğundan, CompareTo metodu 0 döndürerek bu C# IStructuralEquatable nerelerde kullanılıyor dizilerin strüktürel olarak tay olduğunu 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.

Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
However, this is hamiş so great if you are using the struct in a dictionary kakım my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
