ling 中Contains为什么报异常

Question

这是代码：

　　　　List<Guid>list = new List<Guid>();

 var info = from businessUnit in context.CreateQuery<BusinessUnit>()

                               join user1 in context.CreateQuery<crm_User>()

                               on businessUnit.BusinessUnitId equals user1.crm_businessunit_id.Id

                               where list.Contains(businessUnit.BusinessUnitId.Value)

                               select new
                               {
                                  BusinessUnitId = businessUnit.BusinessUnitId,

                                   userName = user1.crm_name,

                                   buName = businessUnit.Name
                               };

Answer 1

Guid转为string试试。我想是不是Guid不能这样比较。

Answer 2

报什么错呢？你的businessUnit.BusinessUnitId.Value不是Guid?

Answer 3

不是，因该是上个页面传过来的！
