c# - 有没有办法在 Where 子句中循环？

Question

有两个列表"ObjlistA"和"ObjlistB".

var newList = from someObg i ObglistB
       where [condition = true if some property of any element in the list ObjlistAA equals  someObg's some property]
       select someObg

有没有办法在 where 子句中循环，以便可以将 obj 的属性与列表中的每个元素的属性进行比较？谁能帮我解决“在哪里”部分？

Answer 1

这是你要找的吗？

var newList = ObjlistB.Where(someObj => ObjlistA.Any(a => a.SomeProperty == someObj.SomeProperty))

Answer 2

where ObjlistA.Any(x => x.Property == someObj.Property)

Answer 3

你是这个意思？

    var newList = from someObg in ObjlistB
                  where ObjlistA.Any(a => a.ID == someObg.ID)
                  select someObg;
