Comparing two List for equality

Question

Other than stepping through the elements one by one, how do I compare two lists of strings for equality (in .NET 3.0):

This fails:

Answer 1

Using Linq and writing the code as an extension method :

public static bool EqualsOtherList(this List thisList, List theOtherList)
{
  if (thisList == null || theOtherList == null || 
      thisList.Count != theOtherList.Count) return false;
  return !thisList.Where((t, i) => !t.Equals(theOtherList[i])).Any();
}
