Title Body

I want to pass a list of strings from IronPython 2.6 for .NET 2.0 to a C# program (I'm using .NET 2.0 because I'm working with an api that runs off of DLLs built on 2.0). But I'm not sure how to cast it as it comes back from the ScriptEngine. namespace test1 { class Program { static void Main(string[] args) { ScriptEngine engine = Python.CreateEngine(); ScriptSource source = engine.CreateScriptSourceFromFile("C:\\File\\Path\\To\\my\\script.py"); ScriptScope scope = engine.CreateScope(); ObjectOperations op = engine.Operations; source.Execute(scope); // class object created object classObject = scope.GetVariable("MyClass"); // get the class object object instance = op.Invoke(classObject); // create the instance object method = op.GetMember(instance, "myMethod"); // get a method List<string> result = (List<string>)op.Invoke(method); // call the method and get result Console.WriteLine(result.ToString()); Console.Read(); } } } my python code has a class with a method that returns a python list of strings: class MyClass(object): def myMethod(self): return ['a','list','of','strings'] I get this error: Unable to cast object of type 'IronPython.Runtime.List' to type 'System.Collections.Generic.List`1[System.String]'.
