Random row from Linq to Sql

Question

What is the best (and fastest) way to retrieve a random row using Linq to SQL when I have a condition, e.g. some field must be true?

Answer 1

Came here wondering how to get a few random pages from a small number of them, so each user gets some different random 3 pages.

This is my final solution, working querying with LINQ against a list of pages in Sharepoint 2010. It's in Visual Basic, sorry :p

Dim Aleatorio As New Random()

Dim Paginas = From a As SPListItem In Sitio.RootWeb.Lists("Páginas") Order By Aleatorio.Next Take 3

Probably should get some profiling before querying a great number of results, but it's perfect for my purpose
