ItemsSource属性可以接收一个IEnumerable接口派生类的实例作为自己的值，ItemsSource里存放的是一条一条的数据，列表式控件的条目容器会为这些数据传上外衣，只要为ItemsControl对象设置了ItemsSource属性值，ItemsControl对象就会自动迭代其中的数据元素，为每一个数据元素准备一个条目容器，并使用Binding在条目容器与数据元素之间建立起关联，例子：

界面代码：

    <StackPanel Background="LightBlue">
        <TextBlock Text="Student ID:" FontWeight="Bold"></TextBlock>
        <TextBox x:Name="textBox1"></TextBox>
        <TextBlock Text="Student List:" FontWeight="Bold"></TextBlock>
        <ListBox x:Name="listBoxStudents" Height="110"></ListBox>
    </StackPanel>

        public MainWindow()
        {
            InitializeComponent();

            List<Student> stuList = new List<Student>()
            {
                new Student(){Id=0, Name="daijun", Age=11},
                new Student(){Id=1, Name="Tim", Age=12},
                new Student(){Id=2, Name="Tom", Age=13},
                new Student(){Id=3, Name="Kyle", Age=14},
                new Student(){Id=4, Name="Tony", Age=15}
            };

            listBoxStudents.ItemsSource = stuList;
            listBoxStudents.DisplayMemberPath = "Name";
            Binding binding = new Binding();
            binding.Source = listBoxStudents;
            binding.Path = new PropertyPath("SelectedItem.Id");
            textBox1.SetBinding(TextBox.TextProperty, binding);
        }
