Sql Server Abfrage entspricht in LINQ

Question

Ich versuche, die folgende Abfrage in LINQ zu konvertieren, versuchte verschiedene Links, aber bisher kein Glück. Bitte helfen Sie mit unten:

SELECT T.TASKID, 
    T.TITLE, 
    T.DESCRIPTION, 
    T.DEADLINE, 
    T.CREATEDON, 
    (SELECT EMAIL FROM ASPNETUSERS WHERE ID = T.CREATEDBYUSERID) AS INITIATEDBY 
FROM TBL_TASKMEMBERS AS M 
INNER JOIN TBL_TASKS AS T ON M.TASKID = T.TASKID 
INNER JOIN ASPNETUSERS AS U ON M.USERID = U.ID 
WHERE m.UserId = '95d2f49c-0ae6-4571-9d7b-1c498ad0bfac' 

Vielen Dank im Voraus!

Answer 1

Versuchen Sie folgendes:

var result = 
from member in TBL_TASKMEMBERS 
join task in TBL_TASKS on member.TASKID equals task.TASKID 
join user in ASPNETUSERS on user.ID equals member.USERID 
join usermail in ASPNETUSERS on usermail.ID equals task.CREATEDBYUSERID 
where member.UserId = '95d2f49c-0ae6-4571-9d7b-1c498ad0bfac' 
select new { TASKID = task.TASKID, TITLE = task.TITLE, DESCRIPTION = taks.DESCRIPTION, DEADLINE = task.DEADLINE, CREATEDON = task.CREATEDON, INITIATEDBY = usermail.EMAIL };
