WPF属性与特性的映射(TypeConverter)

标签：

1,定义一个类

public class Human
{
public string Name { get; set; }
public Human Child { get; set; }
}

2在XAML文件中引用

<Window.Resources>
<Local:Human x:Key="human" Child="明洋" x:Name="human"></Local:Human>
</Window.Resources>

3添加转换类

public class StringToHumanTypeConverter:TypeConverter
{
public override object ConvertFrom(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value)
{
if(value is string)
{
Human h = new Human();
h.Name = value as string;
return h;
}
return base.ConvertFrom(context, culture, value);
}
}

4引用转化类

[TypeConverterAttribute(typeof(StringToHumanTypeConverter))]
//[TypeConverter(typeof(StringToHumanTypeConverter))]与上面的一样
public class Human
{
public string Name { get; set; }
public Human Child { get; set; }
}

5测试映射

private void Button_Click(object sender, RoutedEventArgs e)
{
Human h1 = (Human)this.FindResource("human");//对应X:Key
MessageBox.Show(h1.Child.Name);
}
