Say we have :
public class someclass
{
   public string name;
   public int age;
}
 
List<someclass> data = new List<someclass>();
How can we query the above using a string predicate like below given that it can be done with LINQ predicates:
var q = data.FilterMethod("age<20 and name = \"bob\" ");

You can use aggregate grouped LInQ operators like:
 
List<someclass> data = new List<someclass>();
 
var resultSet =
    from p in data
    group p by p.name into g
    select new { Name = g.Key, Age < 20 };</pre>
