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 hamiş have to return different values.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

g. MyType and Object) which will still use the identity comparison. I suspect it's not 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

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 derece just compare references or individual values.

You generic method saf a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you emanet use .Safi tuples or anonymous types to create hash codes by combining values C# IStructuralEquatable Temel Özellikleri but I am not sure this answers your question.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I birey just compare each of them":

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.
