问题
with absolutely no knowledge of coding in C#, I wish to call a C# function within my python code. I know there's quite a lot of Q&As around the same problem, but for some strange reason, i'm unable to import a simple c# class library from a sample python module.
Here's below as to what i've done -
C# Class Library setup
I'm using the VS 2017 CE.
I create a new project TestClassLibrary
under the type of ClassLibrary(.NET Standard)
The classes inside the project are as follows -
MyClass.cs
using System;
namespace TestClassLibrary
{
public class MyClass
{
public string function()
{
return "Hello World!";
}
}
}
This was built successfully, generating the .dll
file under the \bin\Debug\netstandard2.0
dir as TestClassLibrary.dll
Now, I switch over to python3.6 (running on a virtualenv, backed with pythonnet 2.3.0)
main.py
import sys
sys.path.append(r"<Ablsloute Path to \bin>\Debug\netstandard2.0")
import clr
clr.AddReference(r"TestClassLibrary")
from TestClassLibrary import MyClass
When i Run python main.py
, the code fails with the error -
Traceback (most recent call last):
File "main.py", line 6, in <module>
from TestClassLibrary import MyClass
ModuleNotFoundError: No module named 'TestClassLibrary'
Should the code be -
import sys
sys.path.append(r"C:\Users\DELL\source\repos\TestClassLibrary\TestClassLibrary\bin\Debug\netstandard2.0")
import clr
clr.AddReference("TestClassLibrary.dll")
from TestClassLibrary import MyClass
I get -
clr.AddReference("TestClassLibrary.dll")
System.IO.FileNotFoundException: Unable to find assembly 'TestClassLibrary.dll'.
at Python.Runtime.CLRModule.AddReference(String name)
But when i ran the code below, the code runs as expected -
import clr
clr.AddReference(r"System.Windows.Forms")
from System.Windows.Forms import MessageBox
MessageBox.Show("Hello World!")
I've no idea of what i might be missing :(
回答1:
This is really janky but how I like to do things that are personal projects. Python lets you send stuff to the command line really easily. C# can be run from command line. You probably see where I'm going with this.
Try adding C sharp to PATH. import os to python. then use this line of code when you want to run the C# script:
os.system("csc nameofscript.cs")
perhaps I've misunderstood, but this is how I would make it work on my machine
