WPF ObservableCollectionT 与 BindingListT

csharp
// 定义一个Person类
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}
// 在ViewModel中声明一个ObservableCollection类型的属性
public class MainViewModel : INotifyPropertyChanged
{
    private ObservableCollection _personList;
    public ObservableCollection PersonList
    {
        get { return _personList; }
        set { _personList = value; OnPropertyChanged(); }
    }
    
    public MainViewModel()
    {
        // 初始化PersonList集合
        PersonList = new ObservableCollection();
        
        // 添加几个Person对象
        PersonList.Add(new Person { Name = "张三", Age = 20 });
        PersonList.Add(new Person { Name = "李四", Age = 25 });
        PersonList.Add(new Person { Name = "王五", Age = 30 });
    }
    
    // INotifyPropertyChanged接口的实现代码省略
