Windows8 检测网络

 

在Windows8 上检测网络很简单用到

NetworkInformation这个类

可以看到这个类里面有以下几个方法和事件

public static event NetworkStatusChangedEventHandler NetworkStatusChanged;//网络连接改变的事件public static IReadOnlyList<ConnectionProfile> GetConnectionProfiles();public static IReadOnlyList<HostName> GetHostNames();//获取HostGetInternetConnectionProfile()//详细网络配置GetConnectionProfiles()//网络概要信息

       var icp = NetworkInformation.GetInternetConnectionProfile();                if (icp != null && icp.NetworkAdapter != null)                {                    var hostname =                        NetworkInformation.GetHostNames().SingleOrDefault(                            hn =>                            hn.IPInformation != null &&                            hn.IPInformation.NetworkAdapter.NetworkAdapterId ==                               icp.NetworkAdapter.NetworkAdapterId);                    System.Diagnostics.Debug.WriteLine("可用网络IP:" + hostname.DisplayName);                    System.Diagnostics.Debug.WriteLine("网络状态:" + icp.GetNetworkConnectivityLevel());                }

使用

NetworkInformation.GetInternetConnectionProfile();获取网络配置后可以得到 NetworkAdapter 网络设备

GetNetworkConnectivityLevel()得到当前网络的状态 他是一个枚举类型具体如下

        // Summary:        //     No connectivity. 没有访问        None = 0,         //        // Summary:        //     Local network access only. 本地网络访问        LocalAccess = 1,        //        // Summary:        //     Limited internet access. This value indicates captive portal connectivity,        //     where local access to a web portal is provided, but access to the Internet        //     requires that specific credentials are provided via the portal. This level        //     of connectivity is generally encountered when using connections hosted in        //     public locations (e.g. coffee shops and book stores).        // 有限的访问        ConstrainedInternetAccess = 2,        //        // Summary:        //     Local and Internet access. internet访问        InternetAccess = 3,

可以用NetworkInformation里面的 NetworkStatusChanged 监听网络改变然后在做相应的处理
