C#中调用python方法

最近由于项目设计,有部分使用Python脚本,所以代码中须要调用python方法。python

1.首先,在c#中调用python必须安装IronPython,在  http://ironpython.codeplex.com/  中下载json

2.对应用程序添加IronPython.dll和Microsoft.Scripting.dll 的引用c#

 

3.调用python:dom

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;

namespace WpfUsingPythonDemo
{
   public  class UsingPython
    {
        private ScriptRuntime pyRuntime = null;
        private  dynamic obj = null;
        public  UsingPython()
        {
            string serverpath = AppDomain.CurrentDomain.BaseDirectory + "frs_main.py";//所引用python路径
            pyRuntime = Python.CreateRuntime();
            ScriptEngine Engine = pyRuntime.GetEngine("python");
            ScriptScope pyScope = Engine.CreateScope(); //Python.ImportModule(Engine, "random");
            obj = Engine.ExecuteFile(serverpath, pyScope);
        }
       public bool ExcutePython()
        {
           try
           {
               if (null != obj)
               {
                   obj.frs_init();//调用frs_main.py中的方法
               }
               else
               {
                   return false;
               }
               return true;
           }
           catch(Exception ex)
           {
               throw ex;
           }
        }
    }
}
Using Python

4.c#中引用的python应该是IronPython,与CPython版本和模块中有差异,因此须要注意使用版本ide

5.由于所使用的python文件中引用了不少模块,因此运行时会找不到python库,在网上查了一下,须要引入搜索路径而且引入库,以下:spa

 public  UsingPython()
        {
            string serverpath = AppDomain.CurrentDomain.BaseDirectory + "frs_main.py";//所引用python路径
            pyRuntime = Python.CreateRuntime();
            ScriptEngine Engine = pyRuntime.GetEngine("python");
       
      
       //手动设置搜索路径 ICollection<string> Paths = Engine.GetSearchPaths(); Paths.Add("//Lib"); Paths.Add("//Lib//site-packages"); Paths.Add(AppDomain.CurrentDomain.BaseDirectory + "frs"); //importpy文件中的库,须要注意前后引用顺序 Engine.ImportModule("sys"); Engine.ImportModule("logging"); Engine.ImportModule("Queue"); Engine.ImportModule("ctypes"); Engine.ImportModule("json"); Engine.ImportModule("os"); ScriptScope pyScope = Engine.CreateScope(); //Python.ImportModule(Engine, "random"); obj = Engine.ExecuteFile(serverpath, pyScope); }

  这是本身摸索找到的解决方案,但愿之后能够有更好的方法。设计
