通过资源将Python嵌入C# [英] Embedding Python in C# via resources

问题描述

我已经解决了一段时间，但似乎无法解决，因此我需要一些帮助！问题是我正在用C#编写程序，但是我需要我创建的Python文件中的函数.这本身没有问题:

I have been working on a problem for a while now which I cannot seem to resolve so I need some help! The problem is that I am writing a program in C# but I require a function from a Python file I created. This in itself is no problem:

...Usual Stuff

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

namespace Program
{
    public partial class Form1 : Form
    {
        Microsoft.Scripting.Hosting.ScriptEngine py;
        Microsoft.Scripting.Hosting.ScriptScope s;
        public Form1()
        {
            InitializeComponent();

            py = Python.CreateEngine(); // allow us to run ironpython programs
            s = py.CreateScope(); // you need this to get the variables

        }

        private void doPython()
        {
            //Step 1: 
            //Creating a new script runtime             
            var ironPythonRuntime = Python.CreateRuntime();

            //Step 2:
            //Load the Iron Python file/script into the memory
            //Should be resolve at runtime
             dynamic loadIPython = ironPythonRuntime.;

             //Step 3:
             //Invoke the method and print the result
             double n = loadIPython.add(100, 200);
             numericUpDown1.Value = (decimal)n;
         }
    }
}

但是，这要求文件"first.py"必须位于程序一旦编译的位置.因此，如果我想共享程序，则必须同时发送可执行文件和python文件，这非常不方便.我想解决此问题的一种方法是，将"first.py"文件添加到资源中并从那里运行...但是我不知道该怎么做，即使可能也是这样.

However, this requires for the file 'first.py' to be wherever the program is once compiled. So if I wanted to share my program I would have to send both the executable and the python files which is very inconvenient. One way I thought to resolve this is by adding the 'first.py' file to the resources and running from there... but I don't know how to do this or even if it is possible.

自然，上面的代码对此不起作用，因为.UseFile方法采用字符串参数而不是byte [].有人知道我会如何进步吗?

Naturally the above code will not work for this as .UseFile method takes string arguments not byte[]. Does anyone know how I may progress?

推荐答案

让我们从可能可行的最简单的事情开始，您将获得一些类似于以下内容的代码:

Lets start with the simplest thing that could possibly work, you've got some code that looks a little like the following:

// ...
py = Python.CreateEngine(); // allow us to run ironpython programs
s = py.CreateScope(); // you need this to get the variables
var ironPythonRuntime = Python.CreateRuntime();
var x = py.CreateScriptSourceFromFile("SomeCode.py");
x.Execute(s);
var myFoo = s.GetVariable("myFoo");
var n = (double)myFoo.add(100, 200);
// ...

，我们想用其他方式替换 var x = py.CreateScriptSourceFromFile(... 行；如果我们可以将嵌入式资源作为字符串获取，则可以使用ScriptingEngine.CreateScriptSourceFromString().

and we'd like to replace the line var x = py.CreateScriptSourceFromFile(... with something else; If we could get the embedded resource as a string, we could use ScriptingEngine.CreateScriptSourceFromString().

得到这个好答案，我们可以得到一些看起来像的东西像这样:

Cribbing this fine answer, we can get something that looks a bit like this:

string pySrc;

var resourceName = "ConsoleApplication1.SomeCode.py";
using (var stream = System.Reflection.Assembly.GetExecutingAssembly()
                          .GetManifestResourceStream(resourceName))
using (var reader = new System.IO.StreamReader(stream))
{
    pySrc = reader.ReadToEnd();
}
var x = py.CreateScriptSourceFromString(pySrc);
