If you are talking about a string Where clause (rather than building the expression etc yourself) - then the Dynamic LINQ Library (in the 3.5 samples, IIRC) should suffice.
Note that the example below is for database usage; but you can use it with LINQ-to-Objects by calling .AsQueryable() on your in-memory data.
