MVVM ObservableCollection<> ListView

目标：在ListView中，设两列，一列表示人的姓名，一列表示年龄，用ObservableCollection<>来实现。

编程：

1）定义类Person

public class ABC:INotifyPropertyChanged    

{        

     #region INotifyPropertyChanged 成员

     public event PropertyChangedEventHandler PropertyChanged;        

    public void RaisePropertyChanged(string PropertyName)        

   {            

        if (PropertyChanged!=null)            

        {                

            PropertyChanged(this, new PropertyChangedEventArgs(PropertyName));            

        }        

    }

    #endregion

        private string name;        

        public string Name        

       {            

           get { return name; }            

           set            

          {                

              if (name!=value)                

             {                    

                    name = value;                    

                    RaisePropertyChanged("IP");                

              }            

          }        

}

        private int age;        

        public int Age        

        {            

               get { return age; }            

               set            

              {                

                    if (age != value)                

                    {                    

                         age = value;                    

                         RaisePropertyChanged("Age");                

                      }            

              }        

       }

        public ABC() { }        

        public ABC(string ip,int age)         {             this.Name = ip;             this.Age = age;         }

2).按照MVVM的模式，设计一个ViewModel，在此类中定义ObservableCollection<>:

public Class PracticeViewModel

{

        public ObservableCollection<ABC> collection = new ObservableCollection<ABC>();
        public void InitialCollection()
        {
            collection.Add(new ABC("Betty", 23));
            collection.Add(new ABC("Jully", 24));
            collection.Add(new ABC("Tom", 25));
        }
        public PracticeViewModel()
        {
            InitialCollection();
        }

}

3).定义数据上下文

            PracticeViewModel vm = new PracticeViewModel();
            this.DataContext = vm.collection;

4).写xaml代码

<ListView ItemsSource="{Binding}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="姓名"  DisplayMemberBinding="{Binding Name}"/>
                    <GridViewColumn Header="年龄"  DisplayMemberBinding="{Binding Age}"/>
                </GridView>
            </ListView.View>
</ListView>

 现在的问题是：还没搞清楚listView的ItemSource里面应该Binding 什么，虽然老师讲了，当时感觉明白了，结果试了试发现还是有问题，继续学习。
