使用mono调用C#中的IronPython对象

标签: c# mono ironpython

我有以下IronPython代码。

class Hello:
    def __init__(self):
        pass
    def add(self, x, y):
        return (x+y)

我需要从C#调用它,我想出了以下代码。

using System;
using IronPython.Hosting;
using IronPython.Runtime;
using IronPython;
using Microsoft.Scripting.Hosting;
using Microsoft.Scripting;

class Hello {
    public static void Main()
    {
        ScriptEngine engine = Python.CreateEngine();
        ScriptSource script = engine.CreateScriptFromSourceFile("myPythonScript.py");
        ScriptScope scope = engine.CreateScope();

        script.Execute(scope);
    }
}

复制IronPython.dll后,运行以下命令。 (我试图运行gacutil,但我得到了一些errors

 dmcs /r:IronPython.dll callipy.cs

但是我收到了一些错误信息如下。

Could not load file or assembly 'Microsoft.Scripting.ExtensionAttribute, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
Missing method .ctor in assembly /Users/smcho/Desktop/cs/namespace/IronPython.dll, type System.Runtime.CompilerServices.ExtensionAttribute

...

似乎IronPython需要Microsoft.Scipting.Core,但是使用mono我不知道该怎么办?

  • C#可以在Mono上运行IronPython对象吗?如果是的话,怎么做?

IronPython不是独立的DLL。它有一些应该与IronPython一起提供的依赖项(它们包含在针对.NET 2.0的最新压缩分发中 - 请参阅IronPython download page):

IronPython.Modules.dll
Microsoft.Dynamic.dll
Microsoft.Scripting.dll
Microsoft.Scripting.Core.dll
Microsoft.Scripting.Debugging.dll
Microsoft.Scripting.ExtensionAttribute.dll

确保您的项目可以找到这些DLL(它目前无法找到,这就是您收到错误的原因)。我从来没有尝试过在Mono上运行IronPython,但它是should work

请注意,针对.NET 4.0的IronPython版本不包含(或需要)Microsoft.Scripting.Core.dll和Microsoft.Scripting.ExtensionAttribute.dll,因为它们的功能已合并到System.Core中。有关详细信息,请参阅this answer
