Dynamic where clause in LINQ - with column names available at runtime

Question

Disclaimer: I\'ve solved the problem using Expressions from System.Linq.Expressions, but I\'m still looking for a better/easier way.

Consider the following situation :

Answer 1

var query = from C in db.Customers select c;

if (seachFirstName)
         query = query.Where(c=>c.ContactFirstname.Contains("Blacklisted"));

if (seachLastName)
         query = query.Where(c=>c.ContactLastname.Contains("Blacklisted"));

if (seachAddress)
         query = query.Where(c=>c.Address.Contains("Blacklisted"));

Note that they aren't mutually exclusive.
