c# - 如何使用 IronPython 将参数传递给 Python 脚本

Question

我有以下 C# 代码，我从 C# 调用 python 脚本:

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Windows.Forms;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;
using IronPython.Runtime;

namespace RunPython
{
    class Program
    {
        static void Main(string[] args)
        {
            ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null);
            ScriptRuntime runtime = new ScriptRuntime(setup);
            ScriptEngine engine = Python.GetEngine(runtime);
            ScriptSource source = engine.CreateScriptSourceFromFile("HelloWorld.py");
            ScriptScope scope = engine.CreateScope();
            source.Execute(scope);
        }
    }
}

我无法理解每一行代码，因为我的 C# 经验有限。我将如何更改此代码以便在运行时将命令行参数传递给我的 python 脚本？

谢谢大家给我指明了正确的方向。出于某种原因，engine.sys 似乎不再适用于更新版本的 IronPython，因此必须使用 GetSysModule。这是我的代码的修订版本，它允许我更改 argv:

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Windows.Forms;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using IronPython.Hosting;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
using IronPython.Runtime;

namespace RunPython
{
    class Program
    {
        static void Main(string[] args)
        {
            ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null);
            ScriptRuntime runtime = new ScriptRuntime(setup);
            ScriptEngine engine = Python.GetEngine(runtime);
            ScriptSource source = engine.CreateScriptSourceFromFile("HelloWorld.py");
            ScriptScope scope = engine.CreateScope();
            List<String> argv = new List<String>();
            //Do some stuff and fill argv
            argv.Add("foo");
            argv.Add("bar");
            engine.GetSysModule().SetVariable("argv", argv);
            source.Execute(scope);
        }
    }
}
