Can you give some quick examples of how to import modules from C#? I
am having issues with import exceptions when I try to do things. The
path to the module is definitely within the sys.path, but I get all
sorts of errors. Here is a snippet of my code:
_script_engine.AddToPath(Path.GetDirectoryName(_scriptPath));
_script_engine.AddToPath(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location));
_script_engine.AddToPath(Path.Combine(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location),
"Lib"));
foreach (string assembly in _assemblies)
_script_engine.SystemState.ClrModule.AddReferenceByPartialName(Path.GetFileNameWithoutExtension(assembly));
foreach (KeyValuePair<string, object> obj in _objects)
__main__.SetVariable(obj.Key, obj.Value);
_script_engine.SystemState.prefix =
Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
_script_engine.Execute("import ScriptHelper");
_script_engine.Execute(string.Format("import {0} as Config",
Path.GetFileNameWithoutExtension(_scriptPath)));
ScriptHelper.py is just a set of simple python functions for grabbing
information about loaded modules, etc. It resides in the current
working directory (same as the EntryAssembly.Location). My problem
comes from something inside the script (which is written to a temp
file by the UI in my simple test app) importing something (which has
been added using the ClrModule.AddReferenceByPartialName). I get a
'Script' is not defined (with Script being a DLL in the working
directory which has been added as a reference).
