熟悉和掌握IPAddress类、IPEndPoint类、IPHostEntry类、DNS类的使用
使用IPAddress类、IPEndPoint类、IPHostEntry类、DNS类的方法，显示中央电视台所有服务器的IP地址信息和本机主机名及相关IP地址。
重点：IPAddress类、IPEndPoint类、IPHostEntry类、DNS类方法和属性的正确使用。
难点：无
MainWindow.xaml
MainWindow.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfApp2
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window
{
Button oldbutton=new Button();
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
Button btn=e.Source as Button;
btn.Foreground = Brushes.Red;
oldbutton.Foreground = Brushes.Black;
oldbutton = btn;
frame_1.Source=new Uri(btn.Tag.ToString(), UriKind.Relative);
}
}
}
其中
实现了按钮点击过后颜色的转变；
实现了界面的跳转。
App.xaml
设置了Label和Border的格式供给Dnspage调用。
