blocks|key|50832|text|除了COM选项之外，您还可以让Python脚本实例化一个xmlrpc服务器-它非常透明，而且您永远不需要在自己的代码中处理"xml“。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|50833|然后，在xmlrpc端，您只需通过.net连接到您的python应用程序-如果在C#中没有合适的方法，只需用IronPython编写一个客户端函数即可。|50834|Python文档中的SimpleXMLRPCServer示例就足够了：|50835|http://docs.python.org/library/simplexmlrpcserver.html|offset|length|50836|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|0|1I|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|S|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|T|8|@]|9|@$H|U|I|V|1|W]]|A|$]]|$1|J|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|G]]]]

Besides the COM option, you could make your Python script instantiate a xmlrpc server - 
it is quite transparent and you never have to deal with "xml" on your own code.

Then, on .net side, you simply connect to your python app via xmlrpc - if there is no suitable way to do that in C#, just write a client function in IronPython.

The SimpleXMLRPCServer example on Python documentation is enough for that:

This might be a lot more work than launching the Python process, but here's an alternate solution.

You can <a href="http://docs.python.org/extending/embedding.html" rel="noreferrer">embed Python</a> into another program. The API is for C and Interop from .NET will probably be a major pain. If you're into a bit of a safer way to handle the native Python API, you can look into <a href="http://www.boost.org/doc/libs/1_46_1/libs/python/doc/" rel="noreferrer"><code>Boost.Python</code></a>, which, among its less advertised features, has <a href="http://wiki.python.org/moin/boost.python/EmbeddingPython" rel="noreferrer">support for embedding</a>.

With these tools, you can write a C++ managed DLL that uses <code>Boost.Python</code> to load the Python interpreter and execute any Python script. Thus, you can execute any Python code directly in the hosting process, eliminating the use of an external process and any form of IPC.

Edit: AFAIK, all you have to add to your installation procedure is the deployment of the Python DLL and <code>Boost.Python</code> DLL.

I think you need to re-evaluate Carlos' answer.
See the section Implementing COM Objects with Python in Mark Hammond's book Python Programming on Win32. 

You should be able to create a COM object, then have .Net interact with it. 

From the book the following will create a COM server with a single method.

<pre><code># SimpleCOMServer.py - A sample COM server - almost as small as they come!
# 
# We expose a single method in a Python COM object.
class PythonUtilities:
 _public_methods_ = [ 'SplitString' ]
 _reg_progid_ = "PythonDemos.Utilities"
 # NEVER copy the following ID 
 # Use "print pythoncom.CreateGuid()" to make a new one.
 _reg_clsid_ = "{41E24E95-D45A-11D2-852C-204C4F4F5020}"

 def SplitString(self, val, item=None):
 import string
 if item != None: item = str(item)
 return string.split(str(val), item)

# Add code so that when this script is run by
# Python.exe, it self-registers.
if __name__=='__main__':
 print "Registering COM server..."
 import win32com.server.register
 win32com.server.register.UseCommandLine(PythonUtilities)
</code></pre>

The book goes on to say ".. you can do this by executing the code as a normal Python script. The easiest way to do this is to open the source file in PythonWin and use the Run command from the File menu. "

I think you need the ActivePython distribution from Activestate to do it.

See this question <a href="https://stackoverflow.com/questions/1054849/consuming-python-com-server-from-net">Consuming Python COM Server from .NET</a>

<a href="https://github.com/pythonnet/pythonnet" rel="nofollow noreferrer">PythonNet</a> should help with this one. It enables you to call python code from C#. 

A cleaner way is to expose the python script via a <a href="http://flask.pocoo.org/" rel="nofollow noreferrer">Flask REST API</a> and consume that from your .NET Application. Don't forget to put <a href="https://pythonhosted.org/Flask-OpenID/" rel="nofollow noreferrer">proper authentication</a> in place.

I have some code written in Python which can not be transferred to a .NET language. I need to call one of these functions from my .NET WinForms application.

Now, I do it by starting the Python script as a separate process and pass parameters to it as command line arguments. It works, but I don't really like this solution. I'd like to improve it to a better one.

Is there any better way to call a function of a <code>.py</code> script from a .NET application? What is the best way to do it?

Note: IronPython is NOT an option for this Python script

Call Python from .NET

我有一些用Python语言编写的代码，这些代码不能转换为.NET语言。我需要从我的.NET WinForms应用程序中调用其中一个函数。现在，我将Python脚本作为单独的进程启动，并将参数作为命令行参数传递给它。它是有效的，但我并不是真的喜欢这个解决方案。我想把它改进成更好的。有没有更好的方法从.NET应用程序调用....
