Fluent query - LINQ
string[] names = { "Tom", "Dick", "Harry", "Mary", "Jay" };
IEnumerable<string> query = names
.Where (n => n.Contains ("a"))
.OrderBy (n => n.Length)
.Select (n => n.ToUpper());
Simple Filter Query
from n in new[] { "Tom", "Dick", "Harry" }
where n.Contains ("a")
select n
Ouput: Harry
