Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
If you want to implement IEquatable in a class hierarchy you yaşama use the following pattern. It prevents derived (including sibling) classes from being equal.
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 birey't be overridden and always compares by reference.
As an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.
Kısaca anlayacağınız “int” kabil, “bool” gibi kadir tipli bir kararsız tekvin etmek istiyorsanız struct yapısını tercih edebilirsiniz.

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 derece 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.
Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.
