我有一个类定义为:

public class Student
{
    public string Id { get; set; }
    public IDictionary<string, string> Attributes { get; set; }
}

我可以很容易地存储一个实例:

//creation
using (var session = store.OpenSession())

    student.Attributes = new Dictionary<string, string>();

    student.Attributes["NIC"] = "studentsNICnumberGoesHere";               
    session.Store(student);
    session.SaveChanges();
}

但是,当我查询如下:

//Testing query on attribute
using (var session = store.OpenSession())
{
    var result = from student in session.Query<Student>()
                 where
                     student.Attributes["NIC"] == "studentsNICnumberGoesHere"
                  select student;

    var test …
