sql - 将 SQL 查询转换为 LINQ

Question

我们如何在 LINQ 中写下查询的等价物？

SELECT          
<<Columns>>         
FROM <<SOME JOINS>>         
AND  ISNULL(t.invoiceTypeID,0) NOT IN (2,3)          

AND EXISTS          
(   
     SELECT TOP 1 1 FROM <<Table name >> WHERE <<Condition>>          
)          

AND NOT EXISTS          
(   
     SELECT TOP 1 1 FROM <<Table name >> WHERE <<Condition>>          
)

AND NOT EXISTS          
(
     SELECT TOP 1 1 FROM <<Table name >> WHERE <<Condition>>        
)
