[jiang]

hello:
the multi-layer structure code:

public class Company
{
    public Company(string _name, Guid _companyId)
    {
        Name = _name;
        CompanyId = _companyId;
        this.BusinessUnits = new List<BusinessUnit>();
    }
    public override string ToString()
    {
        return this.Name;
    }
    public string Name { get; set; }
    public Guid CompanyId { get; set; }
    public List<BusinessUnit> BusinessUnits { get; set; }
}
public class BusinessUnit
{
    public BusinessUnit(string _name, Guid _unitId,string _path)
    {
        Name = _name;
        UnitId = _unitId;
        Path = _path;
        this.Users = new List<User>();
        this.ChildBusinessUnits = new List<BusinessUnit>();
    }
    public override string ToString()
    {
        return this.Name;
    }
    public string Path { get; set; }
    public string Name { get; set; }
    public Guid UnitId { get; set; }
    public List<User> Users { get; set; }
    public List<BusinessUnit> ChildBusinessUnits { get; set; }
}
public class User
{
    public User(string _name, Guid _userId, string _path)
    {
        Name = _name;
        UserId = _userId;
        Path = _path;
    }
    public override string ToString()
    {
        return this.Name;
    }
    public string Name { get; set; }
    public Guid UserId { get; set; }
