Is txtOutput defined using the same case in your page? Try the following:

using System;
using AuthorizeNet.Api.Controllers;
using AuthorizeNet.Api.Contracts.V1;
using AuthorizeNet.Api.Controllers.Bases;
using System.Security.Authentication;
using System.Net;

namespace net.authorize.sample
{
    public class AuthorizeCreditCard
    {
        public static ANetApiResponse Run(String ApiLoginID, String ApiTransactionKey, decimal amount)
        {
            Console.WriteLine("Authorize Credit Card Sample");

            ApiOperationBase<ANetApiRequest, ANetApiResponse>.RunEnvironment = AuthorizeNet.Environment.SANDBOX;

            // define the merchant information (authentication / transaction id)
            ApiOperationBase<ANetApiRequest, ANetApiResponse>.MerchantAuthentication = new merchantAuthenticationType()
            {
                name = "",
                ItemElementName = ItemChoiceType.transactionKey,
                Item = "",
            };

            var creditCard = new creditCardType

                expirationDate  = "0718"
            };

            //standard api call to retrieve response
