However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

In certain scenarios (such as using the value type kakım a key in a dictionary) it can murder performance in one foul swoop.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals güç't be overridden and always compares by reference.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

IStructuralEquatable is quite new and unknown, but C# IStructuralEquatable nerelerde kullanılıyor I read somewhere that it emanet be used to compare the contents of collections and arrays. Am I wrong, or is my .Kemiksiz wrong?

When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

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