WPF中TypeConverter类的使用

前台xaml代码:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:WpfApplication1"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <local:HuMain x:Key="humain" Name="Time" Child="LitterTime">  
        </local:HuMain>
    </Window.Resources>
    <Grid>
        <Button Content="单击我吧" Height="20" Width="100" Name="button1" Click="button1_click" ></Button>
    </Grid>
</Window>

    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void button1_click(object sender, RoutedEventArgs e)
        {
            HuMain t_HuMain = FindResource("humain") as HuMain;
            MessageBox.Show(t_HuMain.Child.Name);
        }
    }

    [TypeConverterAttribute(typeof(NameToHuMainTypeConvert))]
    public class HuMain
    {
        public string Name { get; set; }
        public HuMain Child { get; set; }
    }

    public class NameToHuMainTypeConvert : TypeConverter
    {
        public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
        {
            string name = value.ToString();
            HuMain humain = new HuMain();
            humain.Name = name;
            return humain;
        }
