C# IStructuralEquatable Temel Özellikleri - Genel Bakış

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 derece reason enough to approve a correction edit.

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

g. MyType and Object) which will still use the identity comparison. I suspect it's hamiş a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

Does anyone know what happens if you do hamiş implement iequtalable when using generic collections? 2

In this equating the values in arrays may be same or different but their object references are equal.

Arabirimin dü üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test fiyat ve GetHashCodeeşit olan nesneler için aynı kompozit kodları döndürür.

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:

Kupkuru on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is not guaranteed to be the same across updates or platforms.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

Here the comparison is different for value type arrays and custom arrays. In .Safi 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.
