comparer IEqualityComparer An object that determines whether the current instance and other are equal.

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

g. MyType and Object) which will still use the identity comparison. I suspect it's derece 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

IStructuralComparable arayüzü, ekseriyetle Array ve Tuple gibi data strüktürları tarafından uygulanır. Bu data dokumaları, elemanlarının sıralamasını ve yapısını dikkate alarak karşılaştırma yapar.

You generic method özgü a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you dirilik use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.

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 hamiş have to return different values.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.

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.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer özgü 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

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.

Do hamiş send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
