服务之：urlacl解决服务HttpListener监听url需要管理员

在使用HttpListener 监听url时，如果没有以管理员身份运行可能会抛出异常，无法监听，遇到这个问题时，可以先使用管理员权限的程序将Url注册到urlacl列表，解决普通权限无法开启监听问题

第一步： Netsh http show urlacl。查看有没有需要监听的url

 第二步：添加Url到Urlacl： 例如添加   "http://+:55474/"

 /// <summary>
        /// 注册Url
        /// </summary>
        private void RegisterUrl()
        {
            var netshManger = new NetshManger();
            string url = "http://+:55474/";
            netshManger.AddAddress(url);
        }

 /// <summary>
    /// Netsh管理
    /// </summary>
    public class NetshManger
    {
        /// <summary>
        /// 添加url
        /// </summary>
        /// <param name="address"></param>
        public void AddAddress(string address)
        {
            try
            {
                AddAddress(address, Environment.UserDomainName, Environment.UserName);
            }
            catch (Exception ex)
            {
                Debug.Fail(ex.ToString());
            }
        }

        public void AddAddress(string address, string domain, string user)
        {
            string argsDll = $@"http delete urlacl url={address}";
            string args = $@"http add urlacl url={address} user=everyone";       //{domain}\{user}"
            ProcessStartInfo psi = new ProcessStartInfo("netsh", argsDll)
            {
                Verb = "runas",
                CreateNoWindow = true,
                WindowStyle = ProcessWindowStyle.Hidden,
                UseShellExecute = false
            };
            Process.Start(psi)?.WaitForExit();//删除urlacl

            psi = new ProcessStartInfo("netsh", args)
            {
                Verb = "runas",
                CreateNoWindow = true,
                WindowStyle = ProcessWindowStyle.Hidden,
                UseShellExecute = false
            };
            Process.Start(psi)?.WaitForExit();//添加urlacl
        }
    }
