从C＃调用Python应用程序/脚本 [英] Calling Python app/script from C#

问题描述

我建设，我想实现的 STV（转移单票的）投票。我用OpenSTV表决前的情景，获得巨大成功，但我从来没有使用过编程。

I'm building an ASP.NET MVC (C#) site where I want to implement STV (Single Transferable Vote) voting. I've used OpenSTV for voting scenarios before, with great success, but I've never used it programmatically.

借助 OpenSTV调用脚本谷歌code项目提供了一个Python脚本，允许OpenSTV的使用从其他应用程序：

The OpenSTV Google Code project offers a Python script that allows usage of OpenSTV from other applications:

import sys
sys.path.append("path to openstv package")

from openstv.ballots import Ballots
from openstv.ReportPlugins.TextReport import TextReport
from openstv.plugins import getMethodPlugins

(ballotFname, method, reportFname) = sys.argv[1:]

methods = getMethodPlugins("byName")
f = open(reportFname, "w")

try:
    b = Ballots()
    b.loadUnknown(ballotFname)
except Exception, msg:
    print >> f, ("Unable to read ballots from %s" % ballotFname)
    print >> f, msg
    sys.exit(-1)

try:
    e = methods[method](b)
    e.runElection()
except Exception, msg:
    print >> f, ("Unable to count votes using %s" % method)
    print >> f, msg
    sys.exit(-1)

try:
    r = TextReport(e, outputFile=f)
    r.generateReport();
except Exception, msg:
    print >> f, "Unable to write report"
    print >> f, msg
    sys.exit(-1)

f.close()

有我从我的C＃ASP.NET MVC网站做​​出这样一个Python电话？一种方法

如果是这样，怎么样？

在此先感谢！

推荐答案

这里是关于如何从C＃中，包括传递参数和返回结果调用IronPython的一个很好的例子;当然，你必须作出这样的code到一个函数，用 ballotFname 和 reportFname 作为参数

Here is a good example on how to call IronPython from C#, including passing arguments and returning results; of course you'll have to make that code into a function, with ballotFname and reportFname as its arguments.
