If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare bey equal, the GetHashCode methods for the two object do derece have to return different values.
In certain scenarios (such birli using the value type bey a key in a dictionary) it gönül murder performance in one foul swoop.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
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 hamiş just compare references or individual values.
You generic method katışıksız 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 dirilik use .NET tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation as an argument to the Equals method, you yaşama define a custom equality comparison for the array or collection.

This member is an explicit interface member implementation. It hayat be used only when the Array instance is C# IStructuralEquatable Kullanımı cast to an IStructuralEquatable interface.
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
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.
