ObjectDataProvider 提供了一种简便的方法，可在 XAML 中创建对象并将对象用作绑定源对象，但不会替换现有的数据模型

使用 ObjectDataProvider

准备一个枚举类



1 public enum EWeekDay
 2     {
 3         星期一,
 4 
 5         星期二,
 6 
 7         星期三,
 8 
 9         星期四,
10 
11         星期五,
12 
13         星期六,
14 
15         星期天,
16     }


准备一个颜色转换器



1  public class Converter : IValueConverter
 2     {
 3         public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
 4         {
 5             PropertyInfo propertyInfo = (PropertyInfo)value;//从这里也可以看出 ObjectDataProvider就是使用的反射机制
 6             var str = propertyInfo.GetValue(value).ToString();
 7             var color = (Color)ColorConverter.ConvertFromString(str);
 8             var brush = new SolidColorBrush(color);
 9             return brush;
10         }
11 
12         public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
13         {
14             throw new NotImplementedException();
15         }
16     }
