使用动态关键字从C#运行IronPython对象

Question

我有以下IronPython代码.

class Hello:
    def __init__(self):
        pass
    def add(self, x, y):
        return (x+y)

我可以使用以下C#代码来使用IronPython代码.

static void Main()
{

    string source = GetSourceCode("ipyth.py");
    Engine engine = new Engine(source);
    ObjectOperations ops = engine._engine.Operations;

    bool result = engine.Execute();
    if (!result)
    {
        Console.WriteLine("Executing Python code failed!");
    }
    else
    {
        object klass = engine._scope.GetVariable("Hello");
        object instance = ops.Invoke(klass);
        object method = ops.GetMember(instance, "add");
        int res = (int) ops.Invoke(method, 10, 20);
        Console.WriteLine(res);
    }

    Console.WriteLine("Press any key to exit.");
    Console.ReadLine();
}

我可以使用动态DLR使这段代码更简单吗？

该IronPython的行动中书有在<15.4.4动态对象进行交互的未来>关于它的简单的解释,但我无法找到一些例子.

是的,动态可以使您的代码更简单

        var source =
            @"
class Hello:
def __init__(self):
    pass
def add(self, x, y):
    return (x+y)

";

        var engine = Python.CreateEngine();
        var scope = engine.CreateScope();
        var ops = engine.Operations;

        engine.Execute(source, scope);
        var pythonType = scope.GetVariable("Hello");
        dynamic instance = ops.CreateInstance(pythonType);
        var value = instance.add(10, 20);
        Console.WriteLine(value);

        Console.WriteLine("Press any key to exit.");
        Console.ReadLine();
