[Win]ListBox数据源绑定 List<T> 或者Collection

Question

我在程序中用了一个List<T>存储临时数据，数据是用按钮加输入框产生的。//构造函数中
    {
            this._items = new List<TestItem>();
            this.listBox1.DataSource = this._items;
            this.listBox1.DisplayMember = "ID";
            this.listBox1.ValueMember = "Name";
     }//Item 类
    public class TestItem
    {
        private int id;
        private string name;        public int ID
        {
            get
            {
                return id;
            }
            set
            {
                id = value;
            }
        }        public string Name
        {
            get
            {
                return name;
            }
            set
            {
                name = value;
            }
        }
    }
把List换成自己派生的Collection也不行；是不是ListBox不支持绑定啊？自己维护数据太累

Answer 1

TestItem最好实现一下IPropertyChanged接口。

Answer 2

用BindingList吧。
//TestItem.cs
public class TestItem : INotifyPropertyChanged
{        private int id;
        private string name;
        public event PropertyChangedEventHandler PropertyChanged;        public void NotifyPropertyChanged(string info)
        {
            if(PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(info));
        }        public int ID
        {
            get { return id; }
            set
            {
                id = value;
                NotifyPropertyChanged("ID");
            }
        }
        public string Name
        {
            get { return name; }
            set
            {
                name = value;
                NotifyPropertyChanged("Name");
            }
        }
          
}// Form1.cs
private BindingList<TestItem> _items;
private int n = 1;
public Form1()
{
            InitializeComponent();
}private void Form1_Load(object sender, EventArgs e)
{
            _items = new BindingList<TestItem>();
            listBox1.DataSource = _items;
            listBox1.DisplayMember = "Name";
            listBox1.ValueMember = "ID";
}private void button1_Click(object sender, EventArgs e)
{            _items.Add(new TestItem { ID = n++, Name = "name" + n });
}
