今天在园子看到一篇关于MVVM的文章，顺便实践了下，代码如下：
Model:
public class Person
{
public int age { get; set; }
public string name { get; set; }
}
代码
using System.ComponentModel;
using System.Collections.ObjectModel;
public class Persons
{
public List<Person> person;
public List<Person> getPerson()
{
person = new List<Person>()
{
new Person{name="Yuanyuan",age=23},
new Person{name="Yoyo",age=28},
new Person{name="Me",age=30}
};
return person;
}
}
ViewModel:
代码
using sl20100820.Model;
using System.Collections.Generic;
using System.ComponentModel;
using System.Collections.ObjectModel;
public class PageViewModel:INotifyPropertyChanged
{
public List<Person> Human { get; set; }
public PageViewModel()
{
Human = new Persons().getPerson();
}
private Person _getOnePerson;
public Person GetOnePerson
{
get { return _getOnePerson;}
set {_getOnePerson=value;
if(PropertyChanged !=null)
{
PropertyChanged(this,new PropertyChangedEventArgs("GetOnePerson"));
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
}
View:
代码
