深入浅出PF 学习笔记---TypeConverter

1. StringToHumanTypeConverter类（从TypeConverter继承

2. using System;
   using System.Collections.Generic;
   using System.ComponentModel;
   using System.Linq;
   using System.Text;
   using System.Threading.Tasks;
   
   namespace WpfStudy2018
   {
       /// <summary>
       /// 将string类型转成Human
       /// </summary>
       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.ToString();
                   return h;
               }
               
               return base.ConvertFrom(context, culture, value);
           }
       }
   }
   

   　　

3. Human类

4.  [TypeConverterAttribute(typeof(StringToHumanTypeConverter))]
       public class Human
       {
           public string Name
           {
               get;
               set;
           }
   
           public Human Child
           {
               get;
               set;
           }
       }

    

5. 前端引用： xmlns:local="clr-namespace:WpfStudy2018"
6. 前段代码：

   <Window.Resources>
           <local:Human x:Key="Snow" Name="zhouyg" Child="Jack"></local:Human>
     </Window.Resources>

    

7. 后台代码：Human h =   this.FindResource("Snow") as Human;
