public Class Company
{
    public IList<Employee> Employees;
}

public Class Employee
{
    public Company WorkPlace;
}

当我想保存类公司的对象时：

MongoDatabase Database = MongoServer.GetDatabase("db");

var workPlace = new Company();

var employee = new Employee { WorkPalce = workPlace}    
workPlace.Employees = new List<Employee>{ employee };

Database.GetCollection<Company>("company").Save(workPlace);

将抛出StackOverFlow异常.
