Sharepoint : Get User's Permission for Lists

Hi this is a small program that print the permission for a given user in a sharepoint site
this helps the admins to know whether a user has access to a particular list and what access.

This simply helps to know what a user can do in each list.

using System.Text;
using Microsoft.SharePoint;

namespace PermissionViewer
{
    class Program
    {
        static void Main(string[] args)
        {
            //Get the site url
            Console.Write("Enter Site Url  : ");
            string siteURL = Console.ReadLine();

            //Get the user name of user
            Console.Write("Enter User Name : ");
            string UserName = Console.ReadLine();

            try
            {
                //Get the sharepoint site
                using (SPSite sharepointSite = new SPSite(siteURL))
                {
                    //open the site
                    using (SPWeb sharepointweb = sharepointSite.OpenWeb())
                    {
                        //Get each and every list in sharepoint site
                        foreach (SPList sharepointList in sharepointweb.Lists)
