Question

我正在尝试将此SQL查询转换为LINQ，但是我能得到的最多是联接表。之后，我无法弄清楚WHERE部分的语法或如何将其作为列表返回（ToList（））。

var groups = db.ENG_Hazmanifest.SqlQuery("SELECT ENG_Hazmanifest.*, 
ENG_Locations.sitenumb FROM ENG_Hazmanifest INNER JOIN ENG_Locations ON 
ENG_Hazmanifest.site = ENG_Locations.id WHERE ENG_Hazmanifest.display = '1' 
ORDER BY ENG_Hazmanifest.pudate").ToList();

据我所知是：

var groups = from ENG_Hazmanifest in db.ENG_Hazmanifest 
                          join ENG_Locations in db.ENGI_Locations
                          on ENG_Hazmanifest.site equals ENG_Locations.id

我需要添加什么？

想通了。

var groups = from ENG_Hazmanifest in db.ENG_Hazmanifest
                          where ENG_Hazmanifest.display == '1'
                          join ENG_Locations in db.ENGI_Locations
                          on ENG_Hazmanifest.site equals ENG_Locations.id select ENG_Hazmanifest;

使用ToList（）将SQL查询转换为LINQ
