Is it possible to format the results of a query using a Lambda Expression?
var results = userRepository.Get(u => u.Username == "JDoe" && u.Password == "123456");

Expression<Func<User,string>> userDisplay = u => u.Firstname + " " + u.LastName + " - " + u.CompanyName

var formatedResults = results.Format(userDisplay);

public class SearchResult
{
     object EntityId {get; set;}
     object Displaytext {get; set;}

}

Func<User,string>> userDisplay = u => u.Firstname + " " + u.LastName + " - " + u.CompanyName;

var formatedResults = results.Select(userDisplay);

var formattedResults = results.Select(x=> new SearchResult { EntityId = x.Id, DisplayText = userDisplay(x){);
//anonymous type
var formattedResults = results.Select(x=> new { EntityId = x.Id, DisplayText = x.ToString()});
