How to filter a parameter that contains numbers? C# .NET

If the QnA result replies with "111card.json" I need the 111 to be identified await and forward to a separate class object then return.

[LuisIntent("it.support")]
public async Task ITSupportIntent(IDialogContext context, LuisResult result)       
{
        var qnaResult = itKB.GetAnswer(result.Query);

        if (qnaResult.ToLower().Contains("111") || 
            qnaResult.ToLower().Contains("222") || 
            qnaResult.ToLower().Contains("333")) 
        {

Currently have the above but not sure if this will work. It should be able to identify the 111 which is part of 111card.json.

Bonus points for showing multiple means of filtering (text, numbers, symbols) etc.

This is exactly the kind of thing Regex is great at:

Regex pattern = new Regex(@"(?<num>\d{3})card\.json");
Match match = pattern.Match(qnaResult.ToLower());
if (match.Success)
{
    string num = pattern.Groups["num"].Value;
    // Do something with num
}
else
{
    // No match
}

I'd recommend looking in to Regular Expressions.

using System.Text.RegularExpressions;

var patternToMatch = "[0-9]{3}card\.json";
var regex = new Regex(patternToMatch, RegexOptions.IgnoreCase);

if (regex.IsMatch(qnaResult))
{
    // Do something...
}
