Question

我尝试在自定义控件中使用枚举类型作为依赖项属性，但始终会出错：

public enum PriceCategories
    {
        First = 1,
        Second = 2,
        Third = 3,
        Fourth = 4,
        Fifth = 5,
        Sixth = 6
    }
    public static readonly DependencyProperty PriceCatProperty =
DependencyProperty.Register("PriceCat", typeof(PriceCategories), typeof(CustControl), new PropertyMetadata(PriceCategories.First));
};

    public PriceCategories PriceCat  // here I get an error "Expected class, delegate, enum, interface or struct"
    {
        get { return (PriceCategories)GetValue(PriceCatProperty); }
        set { SetValue(PriceCatProperty, value); }
    }

拜托，看。错误在哪里？

Answer 1

您的DP未在类的范围内声明。 DP声明后看起来你有一个额外的闭合支撑。

public enum PriceCategories
{
  // ...
}
public static readonly DependencyProperty PriceCatProperty =
  DependencyProperty.Register("PriceCat", typeof(PriceCategories),
  typeof(CustControl),  new PropertyMetadata(PriceCategories.First));
};  // <-- this is probably closing the containing class

使用enum作为WPF中的依赖项属性
