有人能帮我弄清楚WPF的抚养财产系统吗?
假设 A 类有名为“ A_ property ” 的财产( DP) 。 另一类 B 代表了某种商业逻辑, 我希望这类能够监控“ A_ property ” 。 我的意思是, B 类应该订阅 A 类 财产 。 如果有人这么好, 请给我一个样本, 如何使用抚养财产系统?
P.S.我清楚地知道,如何用Event公路解决上述问题,但在我看来,DP系统应该简化解决办法。
提前感谢!
您可以为此使用 DefaitunityPropertystructionor :
var descriptor = DependencyPropertyDescriptor.FromProperty(A.AProperty, typeof(A));
descriptor.AddValueChanged(...);
