C# StructuralComparisons Kullanımı Ile ilgili detaylı notlar

Wiki Article

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

I am trying to have struct birli a property in my class, and want to check to see if the struct is equal to the value I am trying to assign it to, before I go ahead and do so, so I am not indicating the property özgü changed when it hasn't, like so:

C# StructuralComparisons Gets a predefined object that performs a structural comparison of two objects.

Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

I don't believe there is a commonly used pattern to describe this. I would think of it birli "broken composite pattern", because it seems to me that they nearly use the composite pattern and if they actually used it then it would work better.

Similarly, two distinct arrays will always işleyen an equality test—unless you use a custom equality comparer. Framework 4.0 introduced one for the purpose of comparing elements in arrays which you kişi access via the StructuralComparisons type.

And as a result, default equality checks need two of the compared items to be the same type but StructuralEqualityComparer doesn't require them to be same type. Kakım the name suggests it is supposed to compare contents.

You don't implement explicitly an equality operator, so == is not defined particularly for the type.
