Equality between two enumerables

Question

I have two enumerables with the exact same reference elements, and wondering why Equals wouldn\'t be true.

As a side question, the code below to compare each element

Answer 1

Have a look at the Enumerable.SequenceEqual method.

bool result = AllAccounts.SequenceEqual(other.AllAccounts);

Depending on the data type you may also need to use the overloaded method that accepts an IEqualityComparer to define a custom comparison method.

Answer 2

.Equals is comparing the references of the enumerables, not the elements they contain.
