折腾IronPython 一晚，没搞通

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;


namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }


        private void button1_Click(object sender, EventArgs e)
        {
            string pyfile = @"C:\Users\Administrator\Documents\visual studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\ttt.py";
            pyfile = "ttt.py";


            ScriptEngine Engine = Python.CreateEngine();
            //Engine.Runtime.IO.RedirectToConsole();


            ICollection L = Engine.GetSearchPaths();
            Engine.SetSearchPaths(L);


            ScriptScope scope = Engine.CreateScope();
            var s = Engine.CreateScriptSourceFromFile(pyfile).Compile().Execute(scope);


            MessageBox.Show(s);
            return;
        }






    }

}

1：总提示缺少库文件，实际上路径都有

2：不知道怎么执行py里1个方法，和加参数
