datagridview 绑定复杂对象

C# code

public class User
    {
        public User()
        {
        }
        public User(int vAge,string vName)
        {
            _Age=vAge;
            _Name=vName;
        }
        private int _Age;
        private string _Name;
        public int Age
        {
            set{_Age=value;}
            get{return _Age;}
        }
        public string Name
        {
            set{_Name=value;}
            get{return _Name;}
        }
       private Address _ad = new Address();
       public Address adress
       {
            set{_ad =value;}
            get{return _ad ;}
        }

 
}
public class Address
{
private string _phone;
 public string Phone
{
 get{return _phone;}
set{_phone = value;}
}
}

后来需要在datagridview 里面绑定一个list<User>
我定义了三个column，
name， age， phone。
主要是phone column里面的dataPropertyName 应该写什么？
这种对象里面的属性仍是一个复杂对象怎么处理？


------解决方案--------------------
public User()
{
}
public User(int vAge,string vName)
{
_Age=vAge;
_Name=vName;
}
private int _Age;
private string _Name;
public int Age
{
set{_Age=value;}
get{return _Age;}
}
public string Name
{
set{_Name=value;}
get{return _Name;}
}
private Address _ad = new Address();
public Address adress
{
set{_ad =value;}
get{return _ad ;}
}
public string Phone
{
get{return adress.Phone;}
set{adress.Phone= value;}
}
}
不就可以了吗？？？？？？


------解决方案--------------------
public class SubPropertyDescriptor<T> : PropertyDescriptor
{
#region Fields

private PropertyInfo propertyInfo;

#endregion

#region Constructors

/// <summary>
/// Constructor
/// </summary>
/// <param name="name"></param>
public SubPropertyDescriptor(string name)
: base(name, null)
{
Type t = typeof(T);
this.propertyInfo = null;

string[] subPropertyNames = name.Split('.');
if (subPropertyNames.Length == 1)
{
// a regular property
this.propertyInfo = t.GetProperty(name);
}
else
{
// navigate through the subproperties
for (int i = 0; i < subPropertyNames.Length; ++i)
{
this.propertyInfo = t.GetProperty(subPropertyNames[i]);
t = this.propertyInfo.PropertyType;
}
}
}
