How to use IronPython.Net In C# for Youtube-dl any Sample Code?

[abmspirit]

My Code Is always retunring Null

    ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null);
    ScriptRuntime runtime = new ScriptRuntime(setup);
    ScriptEngine engine = Python.GetEngine(runtime);
    var searchPaths = engine.GetSearchPaths();     
    searchPaths.Add(Server.MapPath("~/Lib"));
    searchPaths.Add(Server.MapPath("~/youtube-dl"));
    engine.SetSearchPaths(searchPaths);
     ScriptSource source = engine.CreateScriptSourceFromFile(Server.MapPath("~/youtube-dl/__main__.py"));
    ScriptScope scope = engine.CreateScope();
    List<String> argv = new List<String>();
    //Do some stuff and fill argv
    argv.Add("--dump-json");
    argv.Add("https://www.youtube.com/watch?v=sxLnf-B7-3w");
    engine.GetSysModule().SetVariable("argv", argv);
    dynamic  x=source.Execute(scope);

Most likely you are doing something wrong as it works fine from console:

The process you have mentioned ,i have to load the process into memory.I used this method with winpython and youtube-dl zipped version and it worked.
But when new request comes to server new instance of python is created in memory and it consumes nearly 20 mb untill it finish the job,So for 10000 request IIS server will be blown away.So i am trying to use this without loading interpreter in memory.I think ironpython.net is known for this.

I'm not telling you must run it as process. I just mentioned this to show that youtube-dl is adapted to work with IronPython and does actually work.
