I use the following for finding a class that implements a certain interface.
IAttributesCollection attrs =
IronPython.Runtime.Types.PythonModuleOps.Get__dict__(__main__);
foreach (KeyValuePair<object, object> attr in attrs)
{
IronPython.Runtime.Types.PythonType attr_type =
attr.Value as IronPython.Runtime.Types.PythonType;
if (attr_type != null)
{
foreach (IronPython.Runtime.Types.PythonType
dt in attr_type.BaseTypes)
{
if (dt.UnderlyingSystemType != null &&
dt.UnderlyingSystemType == typeof(T))
{
CodeContext context = new
CodeContext(__main__.Scope, _context, new ModuleContext(__main__));
inst = (T)attr_type.CreateInstance(context);
break;
}
}
}
}
Is there a way that is more portable between the different languages?
