使用 IronPython 中的 ManagementClass.Getinstances()

发布于 2024-08-25 23:54:36 字数 683 浏览 4 评论 0原文

我有一个 IronPython 脚本，它使用 WMI 查找当前正在运行的进程。代码如下所示：

import clr
clr.AddReference('System.Management')
from System.Management import ManagementClass
from System import Array
mc = ManagementClass('Win32_Processes')
procs = mc.GetInstances()

我调用 GetInstances() 方法的最后一行引发了以下错误：

Traceback (most recent call first):
  File "<stdin>", line 1, in <module>
SystemError: Not Found

我不明白没有找到什么？！？我相信我可能需要将 ManagementOperationObserver 和 EnumerationOptions 的实例传递给 GetInstance() 但是，我不明白为什么会这样，因为具有签名 Getinstance() 的方法在 ManagementClass 中可用。

I have an IronPython script that looks for current running processes using WMI. The code looks like this:

import clr
clr.AddReference('System.Management')
from System.Management import ManagementClass
from System import Array
mc = ManagementClass('Win32_Processes')
procs = mc.GetInstances()

That last line where I call the GetInstances() method raises the following error:

Traceback (most recent call first):
  File "<stdin>", line 1, in <module>
SystemError: Not Found

I am not understanding what's not being found?!? I believe that I may need to pass an instance of ManagementOperationObserver and of EnumerationOptions to GetInstance() however, I don't understand why that is, since the method with the signature Getinstance() is available in ManagementClass.

我认为唯一的问题是“Win32_Processes”是“Win32_Processes”的拼写错误。这似乎有效：

>>> mc = ManagementClass('Win32_Process')
>>> procs = mc.GetInstances()
>>> for p in procs:
...     print p['Name']
... 
System Idle Process
System
smss.exe
(etc)

I think the only problem is that 'Win32_Processes' is a typo for 'Win32_Process'. This seems to work:

>>> mc = ManagementClass('Win32_Process')
>>> procs = mc.GetInstances()
>>> for p in procs:
...     print p['Name']
... 
System Idle Process
System
smss.exe
(etc)
