Linq Inner 加入 Or 子句

Linq Inner join with an Or clause

我有一个 SQL 查询,我想将其转换为 Linq,但我无法弄明白。任何帮助将不胜感激。谢谢

SELECT Distinct Name FROM Context
inner join Nodes_1 on 
Context.Node1Id= Nodes_1.Id OR 
Context.Node2Id= Nodes_1.Id 
where Context.ContextId = 1 

JOINOR 只是两个单独查询 JOINUNION。 因此,要使用 LINQ 重现它,您应该连接两个 linq 查询。

或者您可以这样做:

 var query = (from entry in Context
        from node in Nodes_1
        where node.Id==entry.Node1Id ||
              node.Id==entry.Node2Id
        where entry.ContextId==1
        select entry.Name)
        .Distinct();

这应该适合你:

var something = (from a in Context.Where(i => i.ContextId == 1)
                 from b in Nodes_1 
                 where (a.Node1Id == b.Id) || (a.Node2Id == b.Id)
                 select a.Name).Distinct();
