How do I create a C# event handler that can be handled in IronPython?
如何创建可在IronPython中处理的C＃事件处理程序？
Note that I am using IronPython 2.0.1. I am able to handle events from system classes with no problems (eg Window.KeyDown) but when I try to define my own C# event an exception is raised when I attempt to hook it from IronPython.
请注意，我使用的是IronPython 2.0.1。我能够毫无问题地处理来自系统类的事件（例如Window.KeyDown）但是当我尝试定义自己的C＃事件时，当我尝试从IronPython挂钩时会引发异常。
The exception thrown is ArgumentTypeException and it has the message "cannot add to private event". The message seems odd considering the event I am trying to hook is public.
抛出的异常是ArgumentTypeException，它有消息“无法添加到私有事件”。考虑到我试图挂钩的事件是公开的，这条消息似乎很奇怪。
My C# class looks like this:
我的C＃类看起来像这样：
class Foo
{
...
public event EventHandler Bar;
}
My IronPython setup code looks like this:
我的IronPython设置代码如下所示：
ScriptEngine engine = Python.CreateEngine();
ScriptRuntime runtime = engine.Runtime;
ScriptScope scope = runtime.CreateScope();
ScriptSource source = engine.CreateScriptSourceFromFile("Test.py");
Foo bar = new Foo();
scope.SetVariable("Foo", bar);
source.Execute(scope); <-- Exception is thrown here.
My IronPython script looks like this:
我的IronPython脚本如下所示：
def BarHandler(*args):
pass
Foo.Bar += BarHandler
Does anyone know if I am doing this wrong?
有谁知道我做错了吗？
Or is something wrong with IronPython?
或者IronPython出了什么问题？

I figured it out.
我想到了。
The class needs to be public as well as the event.
课程需要公开以及活动。
eg
例如
public class Foo
{
...
public event EventHandler Bar;
}
