实体框架使用linq返回连接表

Question

我有一些表:

table1:
id1
fk_tb2 // this is the fk to table2

table2:
id2
fk_tb3 //this is the fk to table3

table3:
id3
name3

现在我想返回一个像:id1 fk_tb2 name3的表

谁知道怎么做？谢谢

问候,

Answer 1

连接表并使用匿名类型返回必填字段:

from t1 in table1
join t2 in table2 on t1.fk_tb2 equals t2.id2
join t3 in table3 on t2.fk_tb3 equals t3.id3
select new { t1.id1, t2.id2, t3.name3 }
