datagridview 绑定复杂对象,该如何处理

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？


[解决办法]
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？？？？？？

else
