IronPython（.Net中调用python简述）
IronPython python

官网为：IronPython.net /

环境配置

1、使用visual studio2022创建一个控制台项目 2、打开Nuget管理工具，搜索IronPython

3、记得安装vs的python支持，避免编译失败情况 4、在项目中创建一个PythonScripts的文件夹，用来存放python代码

简单调用

我们可以简单编写程序如下

# main.py
import sys
import uuid

def Test():
    return 'Hello IronPython!'

def SysVersion():
    return sys.version

def CreateUUID():
    return str(uuid.uuid1())

def Print():
    print('Hello World!')

这时在Program.cs中可以输入如下

using System;
using IronPython.Hosting;

var engine = Python.CreateEngine();
dynamic py = engine.ExecuteFile(@"PythonScripts/main.py");

Console.WriteLine("Test:");
var data = py.Test();
Console.WriteLine(data);
Console.WriteLine();


Console.WriteLine("Python & .NET Version:");
var version = py.SysVersion();
Console.WriteLine(version);

Console.WriteLine();

// 使用Python的UUID标准库生成基于时间戳的UUID
Console.WriteLine("Create UUID By Python:");
var uuid = py.CreateUUID();
Console.WriteLine(uuid.ToString());

Console.WriteLine();
var print = py.Print();

如何获取main中变量的值并更改

# main.py
import sys
import uuid

a=10

def Test():
    return 'Hello IronPython!'

def SysVersion():
    return sys.version

def CreateUUID():
    return str(uuid.uuid1())

def Print():
    print('Hello World!')

设置a等于10

var a = py.GetVariable("a");
Console.WriteLine("a的值为"+a.ToString());

py.SetVariable("a", 20);
var v = py.GetVariable("a");
Console.WriteLine("a修改后的值为"+v.ToString());

那如何调用函数并传值呢？

import sys
import uuid

a=10

def Test():
    return 'Hello IronPython!'

def SysVersion():
    return sys.version

def CreateUUID():
    return str(uuid.uuid1())

def Print():
    print('Hello World!')
    
def add_numbers(a,b):
    return a + b

using System;
using IronPython.Hosting;

var engine = Python.CreateEngine();
dynamic py = engine.ExecuteFile(@"PythonScripts/main.py");

Console.WriteLine("Test:");
var data = py.Test();
Console.WriteLine(data);
Console.WriteLine();


Console.WriteLine("Python & .NET Version:");
var version = py.SysVersion();
Console.WriteLine(version);

Console.WriteLine();

// 使用Python的UUID标准库生成基于时间戳的UUID
Console.WriteLine("Create UUID By Python:");
var uuid = py.CreateUUID();
Console.WriteLine(uuid.ToString());

Console.WriteLine();
var print = py.Print();

var a = py.GetVariable("a");
Console.WriteLine("a的值为"+a.ToString());

py.SetVariable("a", 20);
var v = py.GetVariable("a");
Console.WriteLine("a修改后的值为"+v.ToString());

var add_function = py.GetVariable("add_numbers");
int a1 = 5;
int b1 = 3;
var res = add_function(a1, b1);
Console.WriteLine(res);

结果为：
