mysql Query Changing LINQ to Entitities of DB

Hi

Suppose in my example i am considering tbl1 as Entity1 and tb2 as Entity2

List entity1List = new List();
List entity2List = new List();
List filteredList = new List();

Pleas let Entity2 have a property Name

var aaa = ;
var type = ;

filteredList = entity2List.Where(elw => elw.AAA == aaa && elw.Type = type).Select(els => new Entity2() { Id = els.Id, SubmitFlag = els.SubmitFlag, Answer = els.Answer, Name = entity1List.Where(elfw => elfw.QuestionId = els.SecretQuestionId).Select(elf => on.Name).First() }).ToList();
