如何从 IronRuby 类引发 .Net 事件？

我试图弄清楚如何在 ruby 类中实现事件。具体来说，我试图让我的类实现一个包含事件（PropertyChanged）的接口（INotifyPropertyChanged）。我可以创建我的 add_PropertyChanged 和 remove_PropertyChanged 方法...但是然后呢？

这是我的班级到目前为止的样子：

class TestClass
    include System::ComponentModel::INotifyPropertyChanged

    def add_PropertyChanged(handler)
    end

    def remove_PropertyChanged(handler)
    end
end

I'm trying to figure out how to implement an event in a ruby class. Specifically, I am trying to make my class implement an interface (INotifyPropertyChanged) that includes an event (PropertyChanged). I can create my add_PropertyChanged and remove_PropertyChanged methods... but then what?

This is what my class looks like so far:

class TestClass
    include System::ComponentModel::INotifyPropertyChanged

    def add_PropertyChanged(handler)
    end

    def remove_PropertyChanged(handler)
    end
end

好吧，我明白了。操作方法如下：

class TestClass
    include System::ComponentModel::INotifyPropertyChanged

    def initialize
        @change_handlers = []
    end

    def add_PropertyChanged(handler)
        @change_handlers << handler
    end

    def remove_PropertyChanged(handler)
        @change_handlers.delete(handler)
    end

    def NotifyPropertyChanged(name)
        @change_handlers.each { |h| h.invoke(self, System::ComponentModel::PropertyChangedEventArgs.new(name)) }
    end
end

OK, I figured it out. Here is how you do it:

class TestClass
    include System::ComponentModel::INotifyPropertyChanged

    def initialize
        @change_handlers = []
    end

    def add_PropertyChanged(handler)
        @change_handlers << handler
    end

    def remove_PropertyChanged(handler)
        @change_handlers.delete(handler)
    end

    def NotifyPropertyChanged(name)
        @change_handlers.each { |h| h.invoke(self, System::ComponentModel::PropertyChangedEventArgs.new(name)) }
    end
end
