Windows 8 Store Apps学习（60） 通信: 获取网络信息, 序列化和反序列化2014-03-09 cnblogs webabcd介绍

重新想象 Windows 8 Store Apps 之 通信

获取网络信息

序列化 - json

序列化 - xml

序列化 - rss atom

示例

1、演示如何获取网络的相关信息

Communication/NetworkInfo.xaml.cs

/* * 演示如何获取网络的相关信息 */using System;using System.Collections.Generic;using Windows.Networking.Connectivity;using Windows.UI.Xaml.Controls;using Windows.UI.Xaml.Navigation;using System.Linq;namespace XamlDemo.Communication{public sealed partial class NetworkInfo : Page{public NetworkInfo（）{this.InitializeComponent（）;}protected override void OnNavigatedTo（NavigationEventArgs e）{/* * NetworkInformation - 用于对网络信息的访问 */// 获取当前用于 Internet 连接的 ConnectionProfile 对象ConnectionProfile connectionProfile = NetworkInformation.GetInternetConnectionProfile（）;if （connectionProfile == null）return;// 此连接配置的名称lblMsg.Text = "ProfileName: " + connectionProfile.ProfileName;lblMsg.Text += Environment.NewLine;// 此连接的网络连接级别（Windows.Networking.Connectivity.NetworkConnectivityLevel 枚举）// None - 无连接// LocalAccess - 仅允许访问本地网络// ConstrainedInternetAccess - 受限的 internet 访问// InternetAccess - 本地和 internet 访问lblMsg.Text += "NetworkConnectivityLevel: " + connectionProfile.GetNetworkConnectivityLevel（）;lblMsg.Text += Environment.NewLine;// 网络状态发生变化时所触发的事件NetworkInformation.NetworkStatusChanged += NetworkInformation_NetworkStatusChanged;NetworkAdapter networkAdapter = connectionProfile.NetworkAdapter;if （networkAdapter ！= null）{lblMsg.Text += "NetworkAdapterId: " + networkAdapter.NetworkAdapterId; // 网络适配器 IDlblMsg.Text += Environment.NewLine;lblMsg.Text += "InboundMaxBitsPerSecond: " + networkAdapter.InboundMaxBitsPerSecond; // 最大入站数据传输速率（单位：bit/s）lblMsg.Text += Environment.NewLine;lblMsg.Text += "OutboundMaxBitsPerSecond: " + networkAdapter.OutboundMaxBitsPerSecond; // 最大出站数据传输速率（单位：bit/s）lblMsg.Text += Environment.NewLine;lblMsg.Text += "NetworkTypes: " + networkAdapter.NetworkItem.GetNetworkTypes（）; // 网络类型lblMsg.Text += Environment.NewLine;}lblMsg.Text += Environment.NewLine;// 获取所有可用连接IReadOnlyList<ConnectionProfile> connectionProfiles = NetworkInformation.GetConnectionProfiles（）;foreach （ConnectionProfile cp in connectionProfiles）{lblMsg.Text += "ProfileName: " + cp.ProfileName;lblMsg.Text += Environment.NewLine;// 获取此连接的指定时间段内的本地数据的使用情况DataUsage dataUsage = cp.GetLocalUsage（DateTime.Now.AddHours（-1）, DateTime.Now）;lblMsg.Text += "BytesSent: " + dataUsage.BytesSent; // 已发送的字节数lblMsg.Text += Environment.NewLine;lblMsg.Text += "BytesReceived: " + dataUsage.BytesReceived; // 已收到的字节数lblMsg.Text += Environment.NewLine;}// 以下是一些不常用的东西ConnectionCost connectionCost = connectionProfile.GetConnectionCost（）;DataPlanStatus dataPlanStatus = connectionProfile.GetDataPlanStatus（）;NetworkSecuritySettings networkSecuritySettings = connectionProfile.NetworkSecuritySettings;IReadOnlyList<LanIdentifier> lanIdentifiers = NetworkInformation.GetLanIdentifiers（）;}void NetworkInformation_NetworkStatusChanged（object sender）{}}}

用于演示序列化和反序列化的实体类

Communication/Serializer/Product.cs

/* * 用于演示序列化和反序列化的实体类 ** 通过 DataContractJsonSerializer 或 DataContractSerializer 做序列化和反序列化时，其支持 DataContract, DataMember, KnownType * 当然如果都不声明 DataContract, DataMember 也没问题 */using System;using System.Collections.Generic;using System.Runtime.Serialization;namespace XamlDemo.Communication.Serializer{[DataContract（Name="product"）]public class Product{[DataMember（Name = "productId", IsRequired = true, Order = 1）]public int ProductId { get; set; }[DataMember（Name = "name", IsRequired = true, Order = 2）]public string Name { get; set; }public decimal Price { get; set; }[DataMember（Name = "createTime", IsRequired = true, Order = 3）]public DateTime CreateTime { get; set; }public static List<Product> GetProducts（）{List<Product> products = new List<Product>（）;for （int i = 0; i < 5; i++）{products.Add（new Product{ProductId = i,Name = "name: " + i.ToString（）.PadLeft（4, "0"）,Price = i * 100,CreateTime = DateTime.Now.AddDays（-i）}）;}return products;}}}
