Better way of doing multiple cisco commands?

Hi,

I've knocked the following code up to change the vlan on a switchport, is there a more efficient way of doing this rather than declaring a new var each time, also how do I catch the unhandled or should I say the un-expected?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using Renci.SshNet;

namespace SSHTest
{
    class Program
    {
        static void Main(string[] args)
        {

            // Establish connection with the device
            SshClient shell = new SshClient("192.168.0.254", "username", "password");
            shell.Connect();
            if (shell.IsConnected)
            {
                Console.WriteLine("Connected");
            }

            // Create Stream
            var stream = shell.CreateShellStream("dumb", 80, 24, 800, 600, 1024);         
            var resp1 = stream.Expect(new Regex(@".+>$"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp1);

            stream.WriteLine("enable");
            var resp2 = stream.Expect(new Regex("Password:"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp2);

            stream.WriteLine("enablepasswordhere");
            var resp3 = stream.Expect(new Regex(@".+#$"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp3);

            stream.WriteLine("conf t");
            var resp4 = stream.Expect(new Regex(@"\(config\)#"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp4);

            stream.WriteLine("interface FastEthernet0/2");
            var resp5 = stream.Expect(new Regex(@"\(config-if\)"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp5);

            stream.WriteLine("switchport access vlan 1");
            var resp6 = stream.Expect(new Regex(@"\(config-if\)"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp6);

            stream.WriteLine("end");
            var resp7 = stream.Expect(new Regex(@".+#$"), new TimeSpan(0, 0, 5));
            //Console.WriteLine(resp7);

            stream.WriteLine("wr mem");
            var resp8 = stream.Expect(new Regex(@"[OK]"), new TimeSpan(0, 0, 10)); // Extended time for switches with busy cpu
            Console.WriteLine(resp8);

            // Disconnect
            shell.Disconnect();

            Console.WriteLine("Press any key to exit");
            Console.ReadLine();
        }
    }
}
Thanks in advance, and yes I know the code is crude, I'm new to c#.
