IronPythonをホストしているときに__name__を '__main__'に設定するにはどうすればよいですか?

When using IronPython hosted the __name__ special variable returns as instead of __main__. I found some discussion here: http://lists.ironpython.com/pipermail/users-ironpython.com/2006-August/003274.html. But I don't know how to apply it to my code:

public static void RunPythonFile(string filename)
{
   //This is the Key to making sure that Visual Studio can debug
   //the Python script. This way you can attach to 3dsMax.exe
   //and catch exceptions that occur right at the correct location 
   //in the Python script. 
    var options = new Dictionary();
    options["Debug"] = true;

   //Create an instance of the Python run-time
    var runtime = Python.CreateRuntime(options);

   //Retrive the Python scripting engine 
    var engine = Python.GetEngine(runtime);

   //Get the directory of the file 
    var dir = Path.GetDirectoryName(filename);                       

   //Make sure that the local paths are available.
    var paths = engine.GetSearchPaths();                
    paths.Add(dir);
    engine.SetSearchPaths(paths);

   //Execute the file
    engine.ExecuteFile(filename);
}

ホスティングAPIからさらに低レベルの機能を使用する必要があります:

   ScriptEngine engine = Python.CreateEngine();
   ScriptScope mainScope = engine.CreateScope();

   ScriptSource scriptSource = engine.CreateScriptSourceFromFile("test.py", Encoding.Default, SourceCodeKind.File);

   PythonCompilerOptions pco = (PythonCompilerOptions) engine.GetCompilerOptions(mainScope);

   pco.ModuleName = "__main__";
   pco.Module |= ModuleOptions.Initialize;

   CompiledCode compiled = scriptSource.Compile(pco);
   compiled.Execute(mainScope);

var engine = Python.CreateEngine();
var scope = engine.CreateScope();
scope.SetVariable("__name__", "__main__");
var scr = engine.CreateScriptSourceFromString("print __name__", SourceCodeKind.Statements);
scr.Execute(scope);

ファイルから:

var scr = engine.CreateScriptSourceFromFile(fname, Encoding.UTF8, SourceCodeKind.Statements);
