例1-1 DNS域名解析和IP地址轉換的基本用法

例1-2 獲取網絡適配器信息

 

/// <summary>
    /// NetworkInterfacePage.xaml 的交互邏輯
    /// </summary>
    public partial class NetworkInterfacePage : Page
    {
        public NetworkInterfacePage()
        {

                //獲取IPInterfaceProperties實例
                IPInterfaceProperties adapterProperties = adapter.GetIPProperties();

                //獲取並顯示DNS服務器IP地址信息
                IPAddressCollection dnsServers = adapterProperties.DnsAddresses;
                if (dnsServers.Count > 0)

                    }
                }
            }
            textBlock1.Text = sb.ToString();
        }
    }

 

例1-3 網絡流量統計

/// <summary>
    /// IPGlobalStaticsPage.xaml 的交互邏輯
    /// </summary>
    public partial class IPGlobalStaticsPage : Page
    {
        public IPGlobalStaticsPage()
        {
            InitializeComponent();
        }

        private void btn_Click(object sender, RoutedEventArgs e)
        {
            StringBuilder sb = new StringBuilder();
            IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
            IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
            sb.AppendLine("本機註冊域名 : " + properties.DomainName);
            sb.AppendLine("接收數據包數 : " + ipstat.ReceivedPackets);
            sb.AppendLine("轉發數據包數 : " + ipstat.ReceivedPacketsForwarded);
            sb.AppendLine("傳送數據包數 : " + ipstat.ReceivedPacketsDelivered);
            sb.AppendLine("丟棄數據包數 : " + ipstat.ReceivedPacketsDiscarded);
            textBlock1.Text = sb.ToString();
