如何在“LINQ”中创建此sql代码？

Question

select top 10 JobId,Title, 

(SELECT TOP 1 Authorized FROM Company WHERE CompanyId=Job.CompanyId) as CompanyName 

from Job 

如何使这个SQL代码在“LINQ”？

Answer 1

你可以尝试像

var query = (from j in job 
    select new 
    { 
     j.JobId, 
     j.Title, 
     CompanyName = (from c in from Company 
         where c.CompanyId=j.CompanyId) 
         select c.Authorized).First() 
    } 
).Take(10); 

这是假设你将永远有至少有一家公司，否则你可能必须使用FirstOrDefault()。
