C#使用pythonnet简单示例

1.nuget安装pythonnet

2.编写python测试文件 example.py内容如下

def HelloWorld():
     print("Hello world")

class Calculator:
    def add(self,a:float,b:float)->float:
         return a+b

3.c#下测试

    Runtime.PythonDLL = "C:\\Program Files\\Python312\\python312.dll";
    PythonEngine.Initialize();
 
    PythonEngine.BeginAllowThreads();
    

using (Py.GIL())
    {
        string FileName = "example";
        dynamic mymodule = Py.Import(FileName);

        //dynamic py = mymodule.HelloWorld();

        dynamic calculator = mymodule.Calculator();
        float x = calculator.add(12.1, 23.23);

        Log.Logger.Debug($"py cal =  [{x}]  ");
 

    }

4.测试效果，C#控制台输出结果

5.注意 python文件和C#可执行文件必须在同一个目录下才行
