    Object value
)

Remarks

This method determines equality using the default comparer Comparer<T>.Default. Comparer<T>.Default checks whether type T implements System.IComparable<T> and uses that implementation, if available. If not, Comparer<T>.Default checks whether type T implements System.IComparable. If type T does not implement either interface, this method uses Object.Equals.

This method is an O(n) operation, where n is Count.
