C#metro程序如何判断网络是否通？即是否能上网？谢谢！！！最好耗时少。。。

Answer 1

您好！

您可以通过 ConnectionProfile.GetNetworkConnectivityLevel 方法，获取可访问的网络状态。

样例代码如下。

ConnectionProfile profile = NetworkInformation.GetInternetConnectionProfile();
NetworkConnectivityLevel connLevel = profile.GetNetworkConnectivityLevel();
switch (connLevel)
{
	case NetworkConnectivityLevel.None:
		{
			// no internet access
			break;
		}
	case NetworkConnectivityLevel.InternetAccess:
		{
			// internet access is available
			break;
		}
	// other status
	default:
		{
			// other
			break;
		}
}
