Converter sql query to Linq - linq-to-sql

Question

I need to convert this sql query to linq to sql and the result returns a IEnumerable:
select VisualAidName, v.VisualAidID, vs.VisualAidStatusName,
br.BrandName, v.IsEnabled, v.VisualAidCode, v.DateApproved,
br.BrandID, type, UserFirstName+ ' ' + UserLastName as name, AreaID
from VisualAids v inner join VisualAidStatus vs
on v.VisualAidStatusId = vs.VisualAidStatusId
inner join brands br
on v.BrandID = br.BrandId
inner join VisualAids_Areas_Link vareas
on v.VisualAidID = vareas.VisualAidID
left join users us
on v.Owner = us.UserID
where
AreaID IN (
select areaid
from Users inner join Users_Area_Link
on Users.UserID = Users_Area_Link.UserID
where Users.UserID= 3
)
I did this:
IEnumerable<Visual_Aid> visualAll = from v in Context.VisualAids
join vs in Context.VisualAidStatus on v.VisualAidStatusId equals vs.VisualAidStatusId
join br in Context.Brands on v.BrandID equals br.BrandId
join us in Context.Users on v.Owner equals us.UserID into vadis
from x in vadis.DefaultIfEmpty()
select new Visual_Aid()
{
VisualAid_Name = v.VisualAidName,
VisualAid_Id = v.VisualAidID,
VisualAid_StatusName = vs.VisualAidStatusName,
VisualAid_BrandsName = br.BrandName,
VisualAid_IsEnabled = bool.Parse(v.IsEnabled.ToString()),
VisualAid_Code = v.VisualAidCode,
VisualAid_DateApp = v.DateApproved.ToString() ?? "",
VisualAid_BrandId = int.Parse(v.BrandID.ToString()),
VisualAid_Type = v.Type,
VisualAid_Owner = x.UserID == null ? "" : x.UserFirstName + " " + x.UserLastName
};
but I need to do the part of the subquery, ie, I need to include this:
where AreaID IN (
select areaid from Users inner join Users_Area_Link
on Users.UserID = Users_Area_Link.UserID where Users.UserID= 3
)
Anybody know how? thank you very much in advance

Answer 1

You can add this as a where statement:
.......
join us in Context.Users on v.Owner equals us.UserID into vadis
from x in vadis.DefaultIfEmpty()
where (
from user in Context.Users
join userArea in Users_Area_Link
on user.UserID equals userArea.UserID
where user.UserID==3
select userArea.areaid
).Contains(????.AreaID)
select new Visual_Aid()
{
.......
