Getting NUnit AssertionException when verifying list is sorted and items have special characters

I'm getting NUnit.Framework.AssertionException Expected:collection ordered. When trying to verify the sorting is ascending with the next code:

var anotherList = new List<string> { "www.word-edit.officeapps.live.com", "www.wordclouds.com" };
Assert.That(anotherList, Is.Ordered.Ascending);

Is there something I'm doing wrong? Or missing something? Are there another approach I can follow? Thanks in advance.

Thanks, abdul In some cases, if your collection has an UpperCase item, you should use StringComparer.OrdinalIgnoreCase instead of StringComparer.Ordinal

Your test is failing because those strings are not in ascending order. It fails at word-e of first string and wordc of second string where c is before e and hyphen is ignored by default. If you want to include the hyphen in ordering use StringComparer.Ordinal:

Assert.That(anotherList, Is.Ordered.Ascending.Using((IComparer)StringComparer.Ordinal));

Now the test will succeed.
