假设我有一个带有int列表的对象作为其中一个属性:
public class MyObject
{
public List<int> TheList
}
函数接收此对象作为Linq-To-SQL查询的参数,我有:
public static List<MyModel> ConditionalQuery(MyObject TheObject)
{
using (MyDataContext TheDC = new MyDataContext())
{
var TheListBuilder = (from l in TheDC
where l.Property = the elements in the list
select l.ID).ToList();
return new List<MyModel>(TheListBuilder);
}
}
基本上,参数包含一个int列表,我需要将这些int与l.Property匹配。你怎么写这种情况?
感谢您的建议。

where list.Contains(l.Property)
您可以执行多种条件:
var result = (
from l in TheDC.Table
where list1.Contains(l.Property1)
where list2.Contains(l.Property2)
select l.Id
).ToList();
或
var result = (
from l in TheDC.Table
where list1.Contains(l.Property1) && list2.Contains(l.Property2)
select l.Id
).ToList();
