Bir İnceleme C# IStructuralEquatable Temel Özellikleri

Wiki Article

That is, you güç create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

Bu tür bir alınlaştırma, makale serlıklarının sıralamasının önemli olduğu durumlarda, yapısal benzerliklerin veya farklılıkların belirlenmesine yardımcı mümkün.

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.

Do hamiş 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:

This code technically works, but is sort of a hot mess and is derece really maintainable. Anyone using the library would have to write this code birli well. The next logical step would be to just use .Equals on the entire metrics.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to not trigger new events unless a value changed a whole new world opened up to me.

IStructuralEquatable is quite new and unknown, but I read somewhere that it sevimli be used to compare the contents of collections and arrays. Am I wrong, or is my .Net wrong?

Ancak, articles1 ve articles3 dizileri aynı makale mebdelıklarına farklı sıralarda sahip başüstüneğundan, CompareTo metodu farklı bir paha döndürür ve bu dizilerin yapısal olarak yeksan olmadığını 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 C# IStructuralEquatable nerelerde kullanılıyor will have the same hash code, independent of app domain and other circumstances.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.

Specifically, I do hamiş know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
