HELP: How to trim string by sentence (not by character) and add a "more details" link afterwards.

I populated a DataList with a Title (<%# Eval("Title") %>) and Content (<%# Eval("Content" %>) and all is OK. My problem is to how to trim the "Content" so that it only shows part of the string, say only the first 5 sentences, and I would like to add a "more details" link afterwards.
Also, please help me add a url on the "Title", same url of the "more details" link.
