Sort Generic List in Asp.net

Multiply the results of the Comparison by -1?   so to borrow Nullable's example:

For ASC:

MyArticles.Sort(delegate(Article a, Article b)

{

    return a.CreatedDate.Value.CompareTo(b.CreatedDate.Value);

});

for DESC:

MyArticles.Sort(delegate(Article a, Article b)

{

    return a.CreatedDate.Value.CompareTo(b.CreatedDate.Value) * -1;

});
