LINQ to Entities - 查询中的IN子句

Question

可能重复:
Linq to Entities - Sql"IN"子句
如何在Entity framework 4.0中实现SQL"in"

我怎样才能添加WHERE IN语句...

SELECT * FROM myTable WHERE ID IN (1,2,3,4,5)

在实体框架中

Answer 1

用途Contains:

int[] ids = { 1, 2, 3, 4, 5};

var query = db.myTable.Where(item => ids.Contains(item.ID));

或者在查询语法中:

int[] ids = { 1, 2, 3, 4, 5};

var query = from item in db.myTable
            where ids.Contains(item.ID)
            select item;
