这是我今天第三次跑步，这个热门词汇功能语言F＃让我很生气，但当我得到正确的感觉时感觉很好
之前我遇到了递归循环的问题有人提出了前进的方法，现在我得到了上面的错误，问题是我知道我的类型将是一个字符串，那么为什么编译器会抱怨？
目标是将12周的学习付诸实践所以我想在基本的聊天机器人上工作到目前为止我可以进行基本的对话，但是，有一些事情仍然不在我的范围内，例如
为什么我不能打电话给我？ IUserError传递用户输入并检查他们是否说过不在我的主题列表中的内容然后用无效输入回复。
我的另一个问题是保持简单我想将所有输入转换为小写字符串这也被证明是一个挑战。
然后在对话的某个阶段有数字用户到达房间位置由于某种原因我可以找到一种方法而不是做这个检查。
在线教程很少，我使用的书并不能很好地解释。我对迄今取得的成就感到满意
如果有人可以解释我在哪里出错，因为在C＃中这将会消失并且灰尘。:(
这是我的整个代码随时可以讨论：

我不确定使用界面是你想要做的。您没有为IUserError定义任何抽象方法，但是您可能再次将其保存以供日后使用。此外，你有一个匹配块挂在那里没有功能。
以下是我对你能做什么的解释：
// Crossing the stream
type Error = { ErrorMessage:string; ErrorCode:int}
type Success = { Status:string }
type UserError =
| Error of Error
| Success of Success
let printResponse (error:UserError) =
match error with
| Error (e) -> printfn "Code %i \n Message: %s" e.ErrorCode e.ErrorMessage
| Success _ -> printfn "Success"
|_ -> failwith "Invalid option"
let error = Error {ErrorMessage = "Incorrect input please enter a subject phase"; ErrorCode = 250}
使用fsi评估printResponse，它应如下所示：
> printResponse error;;
Code 250
Message: Incorrect input please enter a subject phase
val it : unit = ()
