It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

It is used by the third example as an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare as equal, the GetHashCode methods for the two object do not have to return different values.
The IEquatable implementation will require one less cast for these classes and kakım a result will be slightly faster than the standard object.Equals method that would be used otherwise. Kakım an example see the different implementation of the two methods:
şu demek oluyor ki anlayacağınız “int” üzere, “bool” kadar ayar tipli bir değişken oluşturmak istiyorsanız struct yapkaloriı tercih edebilirsiniz.
The reason why you need the IStructuralEquatable is for defining a new way C# IStructuralEquatable nedir of comparision that would be right for all the objects .
In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the veri and are only really used for reading the data.
Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.
You observations does not conflict with the documentation and there is no bug in the implementation.
