最近由於項目設計,有部分使用Python腳本,所以代碼中須要調用python方法。python
1.首先,在c#中調用python必須安裝IronPython,在 http://ironpython.codeplex.com/ 中下載json
2.對應用程序添加IronPython.dll和Microsoft.Scripting.dll 的引用c#
3.調用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路徑 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();//調用frs_main.py中的方法 } else { return false; } return true; } catch(Exception ex) { throw ex; } } } }
4.c#中引用的python應該是IronPython,與CPython版本和模塊中有差異,因此須要注意使用版本ide
5.由於所使用的python文件中引用了不少模塊,因此運行時會找不到python庫,在網上查了一下,須要引入搜索路徑而且引入庫,以下:spa
public UsingPython() { string serverpath = AppDomain.CurrentDomain.BaseDirectory + "frs_main.py";//所引用python路徑 pyRuntime = Python.CreateRuntime(); ScriptEngine Engine = pyRuntime.GetEngine("python");
//手動設置搜索路徑 ICollection<string> Paths = Engine.GetSearchPaths(); Paths.Add("//Lib"); Paths.Add("//Lib//site-packages"); Paths.Add(AppDomain.CurrentDomain.BaseDirectory + "frs"); //importpy文件中的庫,須要注意前後引用順序 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); }
這是本身摸索找到的解決方案,但願之後能夠有更好的方法。設計
