Environment
- Pythonnet version: 2.3.0
- Python version: 3.6 (Anaconda 32-bit)
- Operating System: Windows 10
Details
I have the following code:
Interface1.cs
using System.Collections.Generic;
public interface Interface1
{
string Test();
List<string> GetList();
List<MyType> GetListOfMyType();
}
public class MyType
{
}Class1.cs
using System.Collections.Generic;
namespace Python.EmbeddingTest
{
public class Class1 : Interface1
{
public string Test()
{
return "test";
}
public List<string> GetList()
{
return new List<string>() { "testing" };
}
public List<MyType> GetListOfMyType()
{
return new List<MyType>() { new MyType(), new MyType() };
}
}
}Module1.py
import clr
clr.AddReference("Python.EmbeddingTest")
from Python.EmbeddingTest import *
class Class2(Class1):
def Test(self):
return "Test from Class2"
def Method1(self):
return "Method1"Test
I am trying to do something like what the following test is trying to do:
[Test]
public void TestGenericListMarshalling()
{
var scope = Py.Import("module1");
var attr = scope.GetAttr("Class2");
dynamic c2 = attr.Invoke();
List<string> ls = c2.GetList();
}Exception
However, I get the following exception:
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException occurred
HResult=0x80131500
Message=Cannot implicitly convert type 'Python.Runtime.PyObject' to 'System.Collections.Generic.List<string>'
Source=Python.EmbeddingTest
StackTrace:

Is it possible to marshall generic .NET Lists?
