轉換SQL查詢Linq查詢左外連接和where子句

Question

我想這個SQL查詢轉換爲LINQ查詢

select 
    prsnRolIDTitle, prprdID 
from 
    Tbl_RoleDetail 
left outer join 
    Tbl_PersonRolPersonRolDetail on Tbl_RoleDetail.prsnRolDID = Tbl_PersonRolPersonRolDetail.prsnRolDID 
           and Tbl_PersonRolPersonRolDetail.prsnRolID = 6 

感謝您的幫助！

Answer 1

也許是這樣的：

from rd in Tbl_RoleDetail 
    from Tbl_PersonRolPersonRolDetail.Where(t => t.prsnRolID = 6 && t.prsnRolDID == rd.prsnRolDID).DefaultIfEmpty() 
    select new {rd.prsnRolIDTitle, prd.prprdID}
