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 works, but there must be a more elegant way
var other = (ActivityService) obj;
if (!AllAccounts.Count().Equals(other.AllAccounts.Count())) return false;
for (int i = 0; i < AllAccounts.Count(); i++) {
if (!AllAccounts.ElementAt(i).Equals(other.AllAccounts.ElementAt(i))) {
return false;
}
}
return true;
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.
.Equals比较了枚举的引用,而不是它们包含的元素 。
