python中C#类库调用+调试方法~~~

因为开发需要，我们经常会用C#来写一些库供python调用，但是在使用过程中难免会碰到一些问题，需要我们抽丝剥茧来解决~~~

首先，我们在python中要想调用C#(基于.net)的dll，需要安装一个库，它就是

pythonnet

这个安装过程就省略了.... 

然后，在python项目的开头，需要作如下引用:

import clr

那我们就以调用hpy-Library.dll为例，我们先看看是否能载入成功~~

sys.path.append(os.getcwd() + r"\windll")    # hpy-Library.dll 文件所在位置
dll_load = clr.AddReference('hpy-Library')print(dll_load)
print(clr._available_namespaces)
print("hpy_Library in namespaces:", "hpy_Library" in clr._available_namespaces)

如果不出意外的话，将会输出以下内容:

hpy-Library, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

hpy_Library in namespaces: True

第一行表示hpy-Library的版本等相关信息

第二行为clr当前激活的名字空间，这里会包含很多.net库的名字空间

第三行即检查hpy_Library是否在available的namespaces中，结果为真即表示dll载入成功，可用。那么下面你就可以开始使用你的C#外部dll库了~~ ex：

sys.path.append(os.getcwd() + r"\windll")    # hpy-Library.dll 文件所在位置
dll_load = clr.AddReference('hpy-Library')#print(dll_load)
#print(clr._available_namespaces)
#print("hpy_Library in namespaces:", "hpy_Library" in clr._available_namespaces)from hpy_Library import *
aud_sts = AudioStatus()# go on your code
