1.前台Grid定义

2.后台代码处理

HostsHelper _helper = new HostsHelper();        public MainWindow()        {            InitializeComponent();            //绑定列表            Rebind();        }        //添加域名和IP绑定        private void Button_Click(object sender, RoutedEventArgs e)        {            string ip = txtIp.Text;            string hostname = txtHostName.Text;            if (string.IsNullOrEmpty(hostname))            {                txtHostName.Focus();                ShowResult("请输入域名");                return;            }            if (string.IsNullOrEmpty(ip))            {                txtIp.Focus();                ShowResult("请输入IP地址");                return;            }            //添加结果            _helper.Add(new HostData(true, ip, hostname));            MessageBox.Show("添加成功");            //重新绑定            Rebind();        }        //重新绑定结果        public void Rebind()        {            gridOne.ItemsSource = _helper.HostDatas;            gridOne.Items.Refresh();        }        //显示结果        public void ShowResult(string str)        {            Result.Content = str;        }        //删除内容        private void Button_Click_1(object sender, RoutedEventArgs e)        {            Button btn = sender as Button;            MessageBoxResult result = MessageBox.Show("确定要删除吗？", "提示", MessageBoxButton.YesNo);            if (result == MessageBoxResult.Yes)            {                _helper.Remove(new HostData(true,btn.Uid.ToString(),btn.ContentStringFormat.ToString()));                Rebind();            }        }
