如何将lambda表达式从Ironpython脚本传递给C构造函数?

假设我解释了这个权利,而action是一个通用委托,下面的工作(包括我使用的存根)。

蟒蛇:

import clr
clr.AddReference("IronPythonDelegates")

import IronPythonDelegates

def camActionPy(camera, time):
  print "Camera: " + str(camera) + ", time: " + str(time)

IronPythonDelegates.CameraAnimation(camActionPy);

CSharp:

namespace IronPythonDelegates
{
    public class Camera{}

    public class CameraAnimation
    {
    private System.Action<Camera, float> animation;

    public CameraAnimation(System.Action<Camera, float> animation)
    {
        this.animation = animation;
        this.animation(new Camera(), 1.5f);
    }
    }
 }

我纠正了上述使用System.Action的方法,它不再需要显式反射。不过有点奇怪。出于某种原因,我可以构造一个用户创建的委托,比如:

explicitTestAction = IronPythonDelegates.TestAction[IronPythonDelegates.Camera, System.Single](camActionPy);
IronPythonDelegates.CameraAnimation(explicitTestAction);

但无法使用System.Action执行此操作。例如

explicitSystemAction = System.Action[IronPythonDelegates.Camera, System.Single](camActionPy)
IronPythonDelegates.CameraAnimation(explicitSystemAction);

ExplicitSystemAction为空。测试被定义为:

public delegate void TestAction<T1, T2>(T1 one, T2 two);

但幸运的是,无论哪种方式,只要做到:

CameraAnimation(System.Action) 

或

CameraAnimation(TestAction)

尽管出于某种原因,我不记得我第一次尝试工作时…
