使用单声道从 C# 调用 IronPython 对象

Calling IronPython object from C# with mono(使用单声道从 C# 调用 IronPython 对象)

问题描述

我有以下 IronPython 代码.

类你好:def __init__(self):经过定义添加(自我，x，y):返回 (x+y)
我需要从 C# 中调用它，我想出了以下代码.
使用系统；使用 IronPython.Hosting；使用 IronPython.Runtime；使用 IronPython；使用 Microsoft.Scripting.Hosting；使用 Microsoft.Scripting；类你好{公共静态无效 Main(){ScriptEngine 引擎 = Python.CreateEngine();ScriptSource script = engine.CreateScriptFromSourceFile("myPythonScript.py");ScriptScope 范围 = engine.CreateScope();脚本.执行(范围)；}}
复制 IronPython.dll 后，我运行以下命令.(我尝试运行 gacutil，但遇到了一些 错误.
<上一页>dmcs/r:IronPython.dll callipy.cs
但是我收到了一些错误信息，如下所示.
<上一页>无法加载文件或程序集Microsoft.Scripting.ExtensionAttribute，Version=2.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35"或其依赖项之一.程序集/Users/smcho/Desktop/cs/namespace/IronPython.dll 中缺少方法 .ctor，键入 System.Runtime.CompilerServices.ExtensionAttribute找不到自定义 attr 构造函数图像:/Users/smcho/Desktop/cs/namespace/IronPython.dll mtoken: 0x0a000080无法加载文件或程序集Microsoft.Scripting.Core，Version=1.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35"或其依赖项之一.无法加载文件或程序集Microsoft.Scripting.Core，Version=1.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35"或其依赖项之一.无法加载文件或程序集Microsoft.Scripting.Core，Version=1.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35"或其依赖项之一....

看来 IronPython 需要 Microsoft.Scipting.Core，但是单声道我不知道该怎么办?

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

IronPython 不是独立的 DLL.它有一些本应与 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 下载页面):

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

确保您的项目可以找到这些 DLL(目前无法找到，这就是您遇到错误的原因).我从未尝试在 Mono 上运行 IronPython，但它应该可以工作.

请注意，面向 .NET 4.0 的 IronPython 版本不包括(或不需要)Microsoft.Scripting.Core.dll 和 Microsoft.Scripting.ExtensionAttribute.dll，因为它们的功能已合并到 System.Core.有关详细信息，请参阅此答案.

I have the following IronPython code.

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

I need to call this from C#, and I came up with the following code.

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);
    }
}

After copying IronPython.dll, I run the following command. (I tried to run gacutil, but I got some errors.

 dmcs /r:IronPython.dll callipy.cs

But I got some error messages as follows.

Could not load file or assembly 'Microsoft.Scripting.ExtensionAttribute, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

It seems like that IronPython needs Microsoft.Scipting.Core, but with mono I don't know what to do?

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