从C#调用Python

using System.Diagnostics;

public void RunPythonScript(string scriptPath, string arguments)
{
    ProcessStartInfo start = new ProcessStartInfo();
    start.FileName = "python"; // 或者是python.exe的完整路径
    start.Arguments = $"{scriptPath} {arguments}";
    start.UseShellExecute = false;
    start.RedirectStandardOutput = true;
    start.RedirectStandardError = true;

    using (Process process = Process.Start(start))
    {
        using (StreamReader reader = process.StandardOutput)
        {
            string result = reader.ReadToEnd();
            Console.WriteLine(result);
        }

        using (StreamReader reader = process.StandardError)
        {
            string error = reader.ReadToEnd();
            if (!string.IsNullOrEmpty(error))
            {
                Console.Error.WriteLine(error);
            }
        }
    }
}

pip install pythonnet

using Python.Runtime;

public void CallPythonFunction()
{
    using (Py.GIL())
    {
        dynamic np = Py.Import("numpy");
        double[] data = { 1.0, 2.0, 3.0 };
        dynamic result = np.array(data);
        Console.WriteLine(result);
    }
}
