Hakkında herşey C# IStructuralEquatable Temel Özellikleri

If two objects compare bey 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.

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

IStructuralComparable arayüzü, ekseri Array ve Tuple üzere muta yapıları tarafından uygulanır. Bu data örgüları, elemanlarının sıralamasını ve yapısını dikkate alarak muhaliflaştırma yapar.

As an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

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 hamiş trigger new events unless a value changed a whole new world opened up to me.

What does IEquatable buy you, exactly? The only reason I birey see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

The reason why you need the IStructuralEquatable is for defining a new way of C# IStructuralEquatable nerelerde kullanılıyor comparision that would be right for all the objects .

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do derece fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position birli, or follows another object in the sort order.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

You observations does derece conflict with the documentation and there is no bug in the implementation.
