C# 从dialog.Slot（）响应时出错

我正在尝试为Alexa制作一个简单的问答游戏，其中向用户展示两个事件，并尝试猜测第一个事件是在第二个事件之前还是之后发生的

游戏需要一个名为“答案”的位置来填充。 我的问题是我的DialogElicitSlot（）方法导致错误，Alexa无法读取响应

任何帮助都是非常感谢的，如果有人有一个类似的工作示例（使用C#），那也将非常好：）

另外，如果有人能告诉我如何使插槽成为代码中所需的值，我将不胜感激。

您在skill tester beta版上测试时得到了这个输入？alexa不能讲课文吗？这是实际问题吗？确切地说：-）。。如果不清楚的话，很抱歉。当我觉得我的技能出现了神奇的错误时，我会在Alexa builder的测试部分看到

设备日志。您需要查看最后4-5个日志，在某个地方会隐藏错误的确切原因，用引号写。您可能会在
