C# 如何为“提供多个条件”；关于；在dotnet核心连接中

如何为dotnet核心连接中的“on”提供多个条件-

from x in this.context.RegulatoryUpdates
join m in this.context.RegulatoryUpdateClient on **x.Id equals m.RegulatoryupdateId  and  id = 25** into m
from z in m.DefaultIfEmpty()

---

您需要创建匿名对象：

from x in this.context.RegulatoryUpdates
join m in this.context.RegulatoryUpdateClient on new { x.Id, id } equals new { Id = m.RegulatoryupdateId, id = 25 } into m
from z in m.DefaultIfEmpty()
