Python调用一个C＃库

本文介绍了Python调用一个C＃库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

任何人都可以分享如何从蟒蛇code调用一个简单的C＃库（实际上它的WPF）工作的例子？ （我一直在使用IronPython的尝试和有太多的麻烦，不支持CPython的图书馆我的Python code使用，所以我想到了周围试图其他方式和Python调用我的C＃code）。

Anyone can share a working example on how to call a simple C# library (actually its WPF) from python code? (I have tried using IronPython and had too much trouble with unsupported CPython library my python code is using so I thought of trying the other way around and calling my C# code from Python).

下面是我用打例如：

using System.Runtime.InteropServices; using System.EnterpriseServices; namespace DataViewerLibrary { public interface ISimpleProvider { [DispIdAttribute(0)] void Start(); } [ComVisible(true)] [ClassInterface(ClassInterfaceType.None)] public class PlotData : ServicedComponent, ISimpleProvider { public void Start() { Plot plotter = new Plot(); plotter.ShowDialog(); } } }

绘图仪是一个WPF的窗户，绘制椭圆

Plotter is a WPF windows that plots an Ellipse

我不知道如何从我的蟒蛇都称呼这种code。有什么建议么？

I don't know how to call this code from my python all. Any suggestions?

推荐答案

它实际上是pretty容易。只要使用的NuGet的UnmanagedExports包添加到您的.NET项目。见sites.google/site/robertgiesecke/Home/uploads/unmanagedexports了解详情。

It is actually pretty easy. Just use NuGet to add the "UnmanagedExports" package to your .Net project. See sites.google/site/robertgiesecke/Home/uploads/unmanagedexports for details.

您可以然后直接出口，而不必做一个COM层。下面是示例C＃code：

You can then export directly, without having to do a COM layer. Here is the sample C# code:

using System; using System.Collections.Generic; using System.Linq; using System.Runtime.InteropServices; using System.Text; using System.Threading.Tasks; using RGiesecke.DllExport; class Test { [DllExport("add", CallingConvention = CallingConvention.Cdecl)] public static int TestExport(int left, int right) { return left + right; } }

您就可以加载DLL，并调用公开的方法在Python（适用于2.7）

You can then load the dll and call the exposed methods in Python (works for 2.7)

import ctypes a = ctypes.cdll.LoadLibrary(source) a.add(3, 5)
