Thanks,
But I tried the new version named IronPython-40877.zip, the problem
still exists. Is this version fixed?
And I tried to use ScriptRuntime.LoadAssembly
--------------------------------
_runtime.LoadAssembly(System.Reflection.Assembly.LoadFile(@"E:\Source
\IronPython_Main\Src\PyDemo\bin\Debug\demo.dll"));
//_engine.SetSearchPaths(new string[] { @"E:\Source
\IronPython_Main\Src\PyDemo\bin\Debug" });
_source =
_engine.CreateScriptSourceFromString("import demo",
Microsoft.Scripting.SourceCodeKind.Statements);
_source.Execute(_scope);
--------------------------------
I got an IronPython.Runtime.Exceptions.ImportException. {"No module
named demo"}
Is my code wrong?
Best Regards
Yongming
