AIMLbot Input string was not in a correct format. C#

Question

I try to make an artificial engine with AIMLbot in C#, but when I say the first word the program breaks and I get the following error:

Exception User-Unhandled System.FormatException: 'Input string was not in a correct format'

at the line

Result result = bot.Chat(request);

The code with the error:

private void Rec(object s, SpeechRecognizedEventArgs e)
{
    string speech = e.Result.Text;
    //richTextBox1.Text = "You: " + speech + Environment.Newline;

    richTextBox1.AppendText("You: " + speech + Environment.Newline);
    Request request = new Request(speech, user, bot);
    Result result = bot.Chat(request);

    richTextBox1.AppendText("AIDA" + result.RawOutput + Environment.Newline + Environment.Newline);
}

I really need some help :))

Answer 1

Your error

Input string was not in a correct format

Tells you that you have something expecting a string but you are not passing it in a string. The exact line that this is failing on tells you that it is

request

that is not a string when you are passing into bot.Chat(request)

You have declared it as a Request thus it is not a string, however it may be null so if you put a break point on that line, debug and step through the code you can inspect the value of request and see what it is.

Hope this helps
