属性

DeclaringType

获取声明 BindableProperty 的类型
DefaultBindingMode

获取默认的 BindingMode。
DefaultValue

获取 BindableProperty 的默认值。
IsReadOnly

获取一个值，该值指示是否从 BindablePropertyKey 创建 BindableProperty。
PropertyName

获取属性名称。
ReturnType

获取 BindableProperty 的类型。

方法

Create(String, Type, Type, Object, BindingMode, BindableProperty+ValidateValueDelegate, BindableProperty+BindingPropertyChangedDelegate, BindableProperty+BindingPropertyChangingDelegate, BindableProperty+CoerceValueDelegate, BindableProperty+CreateDefaultValueDelegate)
