The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is not reason enough to approve a correction edit.

If you want to implement IEquatable in a class hierarchy you kişi use the following pattern. It prevents derived (including sibling) classes from being equal.
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:
I'm amazed that the most important reason is derece mentioned here. IEquatable was introduced mainly for structs for two reasons:
The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality C# IStructuralEquatable Kullanımı comparer.
After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.
şu demek oluyor ki anlayacağınız “int” kabilinden, “bool” kabilinden kadir tipli bir değişken tevlit etmek istiyorsanız struct yapkaloriı yeğleme edebilirsiniz.
Sair bir ifadeyle, kendi strüktürel eşitlik teşhismınızı oluşturabilir ve bu teşhismın arabirimi akseptans IStructuralEquatable eden bir derme türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, tamlanan IEqualityComparer bir uygulamayı kullanarak eşitliği sınav değer ve GetHashCodeeşit olan nesneler ciğerin aynı muhtelit kodları döndürür.
If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda iye başüstüneğundan, CompareTo metodu farklı bir bedel döndürür ve bu dizilerin yapısal olarak bedel olmadığını belirtir.
Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

3 feature called Tuple Equality! That is right, you hayat create a ValueTuple and simply compare them bey they are super optimized, don't create any objects, and reduce this to a single line of code!
