Setting up AIML in asp.net MVC (FormatException error) - asp.net-mvc

Question

Total noob when it comes to using AIML and having a really hard time getting this set up for an asp.net mvc webpage. I have a basic view setup that the user can enter a message in a textbox and I'm trying to get the chatbot to return a response. I've gotten that interaction to work with my text case so I know the function is correctly getting the users response and that I can send back a response and show it in the chatbox, my problem is trying to setup the chatbot to create dynamic responses. Right now in my controller I have:
String filePath = Server.MapPath("~/aimlBot/aiml/");
ChatBot catbot = new ChatBot(filePath);
string ReturnText = catbot.GetOutput(text); //text is just a string no html or fancy stuff in it
and my ChatBot class
Public class ChatBot : Bot
{
private Bot myBot;
private User myUser;
public ChatBot(string filepath)
{
myBot = new Bot();
myUser = new User("Human", myBot);
Initialize(filepath);
}
private void Initialize(string filepath)
{
AIMLbot.Utils.AIMLLoader loader = new AIMLbot.Utils.AIMLLoader(this.myBot);
myBot.isAcceptingUserInput = false;
loader.loadAIML(filepath);
myBot.isAcceptingUserInput = true;
}
public String GetOutput(String input)
{
Request r = new Request(input, myUser, myBot);
Result res = myBot.Chat(r); //breaks here
string response = "Bot: " + res.Output;
return (response);
}
}
the problem I'm getting is at the
Result res = myBot.Chat(r);
the program throws a FormatException
System.FormatException was unhandled by user code
Message=Input string was not in a correct format.

InnerException:
I have No idea what is wrong with my code. I've tried even changing it from the variable string to just a hardcode case like "Hello how are you" which still caused the same exception.

You have everything perfect except the loadSettings function. Please refer the below snippet to clear your problem!
public ChatBot(string filepath)
{
myBot = new Bot();
myBot.loadSettings(); // <----- You have to insert this line to fix the error!
myUser = new User("Human", myBot);
Initialize(filepath);
}
