Sqlserver查询方式翻译为Linq
select * from sys_Tree where id in (1,2,3)
这样的查询语句在linq中怎样写那！

[解决办法]

C# code

int[] intArray = new int [] { 1, 2, 3 };var result = from c in sys_Tree                 where intArray .Contains(c.id)                 select c;
[解决办法]
int[] intArray = new int [] { 1, 2, 3 };
var result = from c in sys_Tree
                where intArray .Contains(c.id)
                select c;

[解决办法]
  
var result = from c in sys_Tree
                where new int[]{ 1, 2, 3 }.Contains(c.id)
                select c;

OR:

var result =sys_Tree.Where(c=>int[]{ 1, 2, 3 }.Contains(c.id));

用ls的第二种lambda表达式，看起来舒服

from u in sys_Tree  
where u.id.Contains(1,2,3)
select u

弱弱的表达下，至今我都不懂什么是lambda表达式，但我写的linq跟楼上所写的一样，不知道是也不是
