Microsoft Dynamics 2011 N：N LINQ查询,其中where子句包含Guid

奇怪的是,这适用于“Where Users.FullName.StartsWith(”Alex“)”. Dynamics CRM SDK LINQ实现不支持where子句中的Guids吗？

有什么建议？

示例代码

using (var service = new OrganizationService("Xrm"))
        {
            using (var xrm = new XrmServiceContext(service))
            {
                var AlexUser = xrm.SystemUserSet.Where(p => p.FullName.StartsWith("Alex")).First();
                var AlexID = AlexUser.Id;

                var Test =
                        from Users in xrm.SystemUserSet
                        join TeamMemberships in xrm.TeamMembershipSet on Users.Id equals TeamMemberships.SystemUserId
                        join Teams in xrm.TeamSet on TeamMemberships.TeamId equals Teams.Id
                        where Users.Id == AlexID     // <-- problematic where clause
                        orderby Users.FullName
                        select new
                        {
                            FullName = Users.FullName,UserID = Users.Id,TeamName = Teams.Name
                        };

                var Test1 = Test.ToList();
            }
        }
