It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
This is really amazing code and works great for .NET Standard libraries. If you are in a .Safi Core 2.1 application there is an even cooler way of doing this:
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 hamiş just compare references or individual values.
You generic method başmaklık a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you birey use .Safi tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.
– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.
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.

Bu örnekte, articles1 ve articles2 dizileri aynı makale mirlıklarına aynı tam malik evetğundan, 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 C# IStructuralEquatable Kullanımı hash code, independent of app domain and other circumstances.
Do not 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.
Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
