问题描述

如何使用CPython在Python.NET中使用泛型。使用使用泛型的Python.NET

How can I get generics to work in Python.NET with CPython. I get an error when using the subscript syntax from Python.NET Using Generics

TypeError: unsubscriptable object

使用Python 2.7.11 + pythonnet == 2.1.0.dev1

With Python 2.7.11 + pythonnet==2.1.0.dev1

>python.exe
Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec  5 2015, 20:32:19) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> from System import EventHandler
>>> from System import EventArgs
>>> EventHandler[EventArgs]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsubscriptable object

我也尝试过pythonnet == 2.0.0并构建用ReleaseWin x86形成github ca15fe8，并得到相同的错误。

I've also tried pythonnet==2.0.0 and building form github ca15fe8 with ReleaseWin x86 and got the same error.

使用IronPython-2.7.5：

With IronPython-2.7.5:

>ipy.exe
IronPython 2.7.5 (2.7.5.0) on .NET 4.0.30319.0 (32-bit)
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> from System import EventHandler
>>> from System import EventArgs
>>> EventHandler[EventArgs]
<type 'EventHandler[EventArgs]'>

推荐答案

您可以显式获得泛型类对象：

You can get the generic class object explicitly:

EventHandler = getattr(System, 'EventHandler`1')

数字表示通用参数的数量。

The number indicates the number of generic arguments.
