问如何将这个SQL转换成ASP.NET MVC的LINQ？

EN

select 
    table1.DIRECTORATE_ID, 
    table2.PLA_NAME + '//' + table1.ENGLISH_DIRECTORATE_CODE as EngCode
from table1
inner join table2 on table1.PLA_ID = table2.PLA_ID order by EngCode

var query = (from t1 table1.DIRECTORATE_ID, table2.PLA_NAME + '//' + table1.ENGLISH_DIRECTORATE_CODE as EngCode
             from table1
             inner join table2 on table1.PLA_ID = table2.PLA_ID order by EngCode)
            .ToList();
