本文介绍了如何在Visual Studio 2010的C#项目中使用IronPython库调用和整合Python函数。通过创建Console应用程序，引入IronPython相关DLL，并编写C#代码来执行Python的定义函数、类，以及从外部Python文件导入并执行函数。示例中展示了如何执行Python的加法函数、打印语句，以及实例化Python类。同时强调了`TestPython.py`文件的位置要求，该文件包含一个返回年份的Python函数。

1.下载IronPython2.7(http://ironpython.codeplex.com/)

2.安装IronPython2.7

3.VS2010创建Console程式，参考引用C:/Program Files/IronPython 2.7/IronPython*.dll,Microsoft.*.dll

如：

4.Console代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using IronPython.Hosting;
using IronPython.Compiler;
using IronPython.Modules;
using IronPython.Runtime;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
namespace PythonConsole
{
class Program
{
static void Main(string[] args)
{
var engine = Python.CreateEngine();
var scope = engine.CreateScope();
//注意要有空格否则会导致缩进对不上位置即expected an indented block 错误
var py = "def adder(arg1,arg2):\n"+" return arg1 + arg2 \n"+"\n"+"def hello(arg1):\n"+" return 'hello'+arg1 \n"+"\n"+"class MyClass(object):\n"+" def __init__(self,value):\n"+" self.value=value\n"; //__init__ 是两个下划线

var code = engine.CreateScriptSourceFromString(py,SourceCodeKind.Statements);
code.Execute(scope);
var adder = scope.GetVariable<Func<object ,object,object >>("adder");
var hello = scope.GetVariable<Func<object,object>>("hello");

var myClass=scope.GetVariable<Func<object,object>>("MyClass");
var myInstance = myClass("IronPython");

Console.WriteLine(adder(1,2));
Console.WriteLine(hello("Mark"));

Console.WriteLine(engine.Operations.GetMember(myInstance,"value"));

engine.CreateScriptSourceFromString("print 'Hello Python'").Execute();
Console.WriteLine();
engine.Execute("print 'Hello World'"); //严格要求没有空格的地方不要加空格

Dictionary<string, object> options = new Dictionary<string, object>();
options["Debug"] = true;

ScriptRuntime pyRuntime = Python.CreateRuntime(options);
dynamic scriptScope = pyRuntime.UseFile("TestPython.py");
Console.WriteLine(scriptScope.getYear());
Console.ReadLine();

}
}
}
