有点。您不能直接从C#代码访问Python方法。除非您正在使用C#4.0和dynamic关键字,否则您将非常非常特别;)。但是,您可以将IronPython类编译为DLL,然后在C#中使用IronPython托管来访问方法(这适用于IronPython
2.6和.NET 2.0)。
创建一个这样的C#程序:
using System;using System.IO;using System.Reflection;using IronPython.Hosting;using Microsoft.scripting.Hosting;// we get access to Action and Func on .Net 2.0 through Microsoft.scripting.Utilsusing Microsoft.scripting.Utils;namespace TestCallIronPython{ class Program { public static void Main(string[] args) { Console.WriteLine("Hello World!"); scriptEngine pyEngine = Python.CreateEngine(); Assembly myclass = Assembly.LoadFile(Path.GetFullPath("MyClass.dll")); pyEngine.Runtime.LoadAssembly(myclass); scriptScope pyScope = pyEngine.Runtime.importModule("MyClass"); // Get the Python Class object MyClass = pyEngine.Operations.Invoke(pyScope.GetVariable("MyClass")); // Invoke a method of the class pyEngine.Operations.InvokeMember(MyClass, "somemethod", new object[0]); // create a callable function to 'somemethod' Action SomeMethod2 = pyEngine.Operations.GetMember<Action>(MyClass, "somemethod"); SomeMethod2(); // create a callable function to 'isodd' Func<int, bool> IsOdd = pyEngine.Operations.GetMember<Func<int, bool>>(MyClass, "isodd"); Console.WriteLine(IsOdd(1).ToString()); Console.WriteLine(IsOdd(2).ToString()); Console.Write("Press any key to continue . . . "); Console.ReadKey(true); } }}创建一个普通的Python类,如下所示:
class MyClass: def __init__(self): print "I'm in a compiled class (I hope)" def somemethod(self): print "in some method" def isodd(self, n): return 1 == n % 2
编译它(我使用SharpDevelop),但是该
clr.CompileModules方法也应该起作用。然后将已编译
MyClass.dll的文件推入已编译的C#程序所在的目录中并运行它。您应该得到以下结果:
Hello World!I'm in a compiled class (I hope)in some methodin some methodTrueFalsePress any key to continue . . .
这包含了Jeff的更直接的解决方案,该解决方案省去了创建和编译一个小的Python“存根”的麻烦,并且还展示了如何创建可访问Python类中的方法的C#函数调用。
