c# – 嵌入IronPython,内置的帮助命令,我的CLR对象

scope.SetVariable("SomeObject",new SomeObject())

要么

engine.Execute("from MyNamespace import SomeObject",scope)

这取决于脚本如何使用它们.我的应用程序组合被添加到引擎

engine.Runtime.LoadAssembly(Assembly.GetExecutingAssembly())

现在一个脚本可以执行帮助(SomeObject)并且转储漂亮的小帮助信息(*),但是它是不完整的.没有一个对象的事件或属性(当然是公开的)出现,并且许多“内置”成员也丢失.

这是奇怪的部分;如果我启动ipy.exe并执行以下命令：

import sys
sys.path.append('<location of my app>')
import clr
clr.AddReferenceToFile('myapp.exe')
from MyNamespace import SomeObject
help(SomeObject)

我得到一个不同的转储,完成所有的失踪成员！

为什么两者不同？

奖金问题：假设我正确地工作,是否可以在我的CLR对象上添加描述性文本到help()的输出？就像你可以从脚本中,你的python本机类??型？我的第一个猜测是DescriptionAttribute,但是没有工作.

(*)显然,一个最终的工作脚本不会这样做,但是在编写/测试脚本时非常有用.

这是一个完整的控制台程序,说明如何使用标准的python库help()导入替换无内部帮助()的站点.
