c# - 在 WPF 中使用枚举作为依赖属性

Question

我尝试在我的自定义控件中使用枚举类型作为依赖属性，但总是出现错误:

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); }
    }

请看。哪里错了？

Answer 1

您的 DP 未在类范围内声明。看起来您在 DP 声明之后有一个额外的右括号。

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
