與各位 PTMC 的開發者們分享，往後在開發交易策略時有更方便的環境。

-------------------------------

前言

InronPython是一种在.NET和Mono上实现的Python语言，使用InronPython就可以在.NET环境中调用Python代码，非常方便。

本文主要介绍在C#中调用Python代码，并使用Python安装的第三方模块。

安装InronPython

要在.NET环境中使用Python，先要安装InronPython（当然也要安装Python），安装很简单，直接下载安装就行。在CodePlex就有下载，下载地址：

还可以把Python Tools for Visual Studio也安装了。

使用

添加引用库

在Visual Studio新建一个工程后，添加引用IronPython.dll和Microsoft.Scripting.dll（位于InronPython的安装目录下，如下图）。

C#代码内嵌Python

最简单的使用方式如下：

var engine = IronPython.Hosting.Python.CreateEngine();
engine.CreateScriptSourceFromString("print 'hello world!'").Execute();

从文件中加载Python代码

一般情况下我们还是要把Python代码单独写在文件中。在工程中新建一个Python文件，如hello.py，并设置其属性Copy to Output Directory的值为Copy if newer。在hello.py下编写如下代码：

def say_hello():
    print "hello!"

def get_text():
    return "text from hello.py"

def add(arg1, arg2):
    return arg1 + arg2

C#代码如下：

var engine = IronPython.Hosting.Python.CreateEngine();
var scope = engine.CreateScope();
var source = engine.CreateScriptSourceFromFile("hello.py");
source.Execute(scope);

var say_hello = scope.GetVariable<Func<object>>("say_hello");
say_hello();

var get_text = scope.GetVariable<Func<object>>("get_text");
var text = get_text().ToString();
Console.WriteLine(text);

var add = scope.GetVariable<Func<object, object, object>>("add");
var result1 = add(1, 2);
Console.WriteLine(result1);

var result2 = add("hello ", "world");
Console.WriteLine(result2);

更详细的使用方法可参考文档和代码例子。

使用Python安装的第三模块

问题

到此为止，程序运行得很顺利。可是好景不长，最近用Python写了个程序要使用rsa加密，在Python中安装了rsa模块（下载地址：https://pypi.python.org/pypi/rsa/3.1.1）后，直接运行Python代码没问题，可是在C#代码调用时就报异常，异常信息如下：

An unhandled exception of type 'IronPython.Runtime.Exceptions.ImportException' occurred in Microsoft.Dynamic.dll
Additional information: No module named rsa

没有找到模块，经过一番google，说是要设置sys.path，如下：

import sys
sys.path.append(r"c:\python27\lib")

照做之后问题依旧。不过想一想，应该是sys.path还没设置对。

解决

先在python代码加上下面几行：

import sys
sys.path.append(r"c:\python27\lib")
print sys.path

运行查看输出，在对比Python环境下的sys.path，果然不一样，问题应该就出在sys.path上了。

在cmd下分别打开python和IronPython(在IronPython安装目录下的ipy64.exe或ipy.exe)，执行import sys;print sys.path，对比输出：

python:

['', 'C:\\Python27\\lib\\site-packages\\setuptools-12.0.3-py2.7.egg', 'C:\\Pytho
n27\\lib\\site-packages\\rsa-3.1.1-py2.7.egg', 'C:\\Python27\\lib\\site-packages
\\pyasn1-0.1.7-py2.7.egg', 'C:\\Windows\\SYSTEM32\\python27.zip', 'C:\\Python27\
\DLLs', 'C:\\Python27\\lib', 'C:\\Python27\\lib\\plat-win', 'C:\\Python27\\lib\\
lib-tk', 'C:\\Python27', 'C:\\Python27\\lib\\site-packages']

IronPython:

['.', 'C:\\Program Files (x86)\\IronPython 2.7\\Lib', 'C:\\Program Files (x86)\\
IronPython 2.7\\DLLs', 'C:\\Program Files (x86)\\IronPython 2.7', 'C:\\Program F
iles (x86)\\IronPython 2.7\\lib\\site-packages']

分别在两个环境在执行import rsa，Python环境正常，IronPython环境下报ImportError: No module named rsa异常。在IronPython环境下执行如下操作：

sys.path.append('C:\\Python27\\lib\\site-packages\\setuptools-12.0.3-py2.7.egg')
sys.path.append('C:\\Python27\\lib\\site-packages\\rsa-3.1.1-py2.7.egg')

再次import rsa，不报异常了。

对应的python代码文件加上如下几行：

import sys
sys.path.append('C:\\Python27\\lib')
sys.path.append('C:\\Python27\\lib\\site-packages\\setuptools-12.0.3-py2.7.egg')
sys.path.append('C:\\Python27\\lib\\site-packages\\rsa-3.1.1-py2.7.egg')
import rsa

再次运行，Ok！
