使用.NET检测互联网连接的最佳方法是什么？

using System;
using System.Net.NetworkInformation;

public class NetworkConnectionChecker
{
    public static bool IsConnectedToInternet()
    {
        NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
        foreach (NetworkInterface networkInterface in interfaces)
        {
            if (networkInterface.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 || networkInterface.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
            {
                if (networkInterface.OperationalStatus == OperationalStatus.Up)
                {
                    return true;
                }
            }
        }
        return false;
    }
}
