Iron Python System.typeloadexception: Could Not Load Type 'system.runtime.compilerservices.closure' From Assembly 'system.core'

I am now working with Iron Python to run python based dll in C#. So I have this line in my C# Code: public void Runpython(string name, string id) { var engine = Python.CreateEng

Solution 1:

you can do the same work whitout IronPython

install your libraries in "C:\Program Files\Python39\python.exe" or any python environment

and try this:

publicstringRun(string scriptFilePatch, string args)
{
    var psi = new ProcessStartInfo();
    psi.FileName = @"C:\Program Files\Python39\python.exe"; // or any python environment

    psi.Arguments = $"\"{scriptFilePatch}\" {args}";

    psi.UseShellExecute = false;
    psi.CreateNoWindow = true;
    psi.RedirectStandardOutput = true;
    psi.RedirectStandardError = true;
    psi.StandardOutputEncoding = Encoding.UTF8;

    string errors = "", result = "";

    using (var process = Process.Start(psi))
    {
        result = process.StandardOutput.ReadToEnd();
        errors = process.StandardError.ReadToEnd();

    }
    StringWriter writer = new StringWriter();
    HttpUtility.HtmlDecode(result, writer);
    string decodedString = writer.ToString();

    return decodedString;
}

Usage:

Run("c:/code/download.py", "\"imageUrl\"\"fileName}"");

and read the arguments in python whit this

Python Code :

import sys
    url = sys.argv[1] #arg {imageUrl} recived from c# code
    fileName = sys.argv[2] #arg {fileName} recived from c# code

and for return data to c# code you should use this :

b = any_object;
sys.stdout.buffer.write(bytearray(b,"utf-8"))
