c# - 从 ThenInclude 中排除空值

Question

我的EF上下文如下

_context.Offices
       .Where( x => x.ID == id )
            .Include( x => x.County)
               .ThenInclude( x => x.Employees)
                    .ThenInclude( s => s.Department)
                        .ThenInclude( m => m.DeptUser )
            .Include( x => x.XYZ);

我的问题是 DeptUser 可以为空。如何排除空项目？
