我正在尝试将一个简单的 C# 命令行实用程序移植到 Python。C# 程序使用一个名为 foobar.dll 的自定义 .Net dll,它通过 I2C 与一些实验室设备连接。C#代码中dll的用法如下:
fooBar.fooProvider provider = new foobar.fooProvider()
fooBar.fooBarLib fooLib = new foobar.fooBarLib(provider, 0x80)
# used below ...
numFloat = fooLib.GetSomething()
# more python ...
fooLib.SetSomething(NumberAsAFloat)
我想过简单地使用 ctypes 来访问 dll,但我认为这不适用于 C#/.Net。由于我们实验室的限制,我需要使用普通的 Python 发行版 + 插件模块(即不是 IronPython 或 CPython。)我查看了 Python for .NET,但我不确定这是否真的有效。我是 .Net 的 n00b,但在 Java、C++ 和 Python 方面拥有丰富的经验。以前有人遇到过这种情况和好的解决方案吗?
编辑:
有了下面的解释,我在 python 解释器中导入了 clr,然后尝试导入 fooBar 库,结果如下:

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
然后解释器崩溃了。这看起来像是一个糟糕的 dll,对吗?
