...Descending
...By(string propertyName)
...Using(IComparer comparer)

Examples of Use

int[] iarray = new int[] { 1, 2, 3 };
string[] sarray = new string[] { "c", "b", "a" };
string[] sarray2 = new string[] ( "a", "aa", "aaa" );
Assert.That(iarray, Is.Ordered);
Assert.That(sarray, Is.Ordered.Descending);
Assert.That(sarray2, Is.Ordered.By("Length"));
