【愚公系列】2023年01月 .NET CORE工具案例-使用pythonnet实现C#和Python的融合调用

import clr
from System import String
from System.Collections import *

import clr
clr.AddReference("System.Windows.Forms")
from System.Windows.Forms import Form

from pythonnet import load
load("coreclr")

import clr

PythonEngine.Initialize();
using (Py.GIL())
{
    dynamic np = Py.Import("numpy");
    Console.WriteLine(np.cos(np.pi * 2));
}

pip install pythonnet

using System;

namespace TestDll
{
    public class MyTest
    {

        public void Print()
        {

            Console.WriteLine("Hello world!!!");
        }

        public void Print(string msg)
        {

            Console.WriteLine($"Hello {msg}!!!");
        }

        public double Add(double x, double y)
        {
            return x + y;

        }
    }

}

# coding:utf-8
import clr

# 引用Dll，不需要添加后缀
clr.AddReference("TestDll")

# TestDll是命名空间，MyTest是命名空间里定义的类
from TestDll import MyTest

# 实例化类
instance = MyTest()
# 无输入及无返回
instance.Print()
# 有输入及无返回
instance.Print("qin")
# 有输入及输出
add_data = instance.Add(1, 1)
print(add_data)
