If I have an object of type MyBull
and a List<MyBull> orig
:
// Just an example
MyBull x = getMeTheObjectWithIdFromDB(9);
orig.add(x);
// Again same? data object
MyBull y = getMeTheObjectWithIdFromDB(9);
Why is this false then?
// This is false, even though all the properties
// of x and y are the same.
orig.Contains<MyBull>(y);
By default objects will expose reference based equality. If you want custom rules, such as equality based on id fields, you need to override the Equals
and GetHashCode
methods.
