C＃是否有扩展属性？

Does C# have extension properties?

例如，我可以一个扩展属性添加到的DateTimeFormatInfo 名为 ShortDateLongTimeFormat 这将返回 ShortDatePattern ++ LongTimePattern ？

For example, can I add an extension property to DateTimeFormatInfo called ShortDateLongTimeFormat which would return ShortDatePattern + " " + LongTimePattern?

推荐答案

没有他们不存在在C＃3.0，并不会在4.0中加入。它的功能要针对C＃，因此它可能在未来某个日期被添加就行了。

No they do not exist in C# 3.0 and will not be added in 4.0. It's on the list of feature wants for C# so it may be added at a future date.

在这一点上，你能做的最好是的getXXX式的扩展方法。

At this point the best you can do is GetXXX style extension methods.
