如何获取网络设备的在线时长？

显示网络设备在线时长的图像

我希望我的c#程序能够显示网络设备的在线时长。我已经尝试过 NetworkInterface 类，但它没有该信息。

尝试使用 DotRas (http://dotras.codeplex.com/)，如网站上所述，“为 C#、VB.NET 和 C++ CLR 项目等 .NET 语言提供远程访问服务 (RAS) 组件”。

通过检查函数 RasGetConnectionStatistics （MSDN 文档）我发现它返回其中包含字段“dwConnectDuration”的结构 (RAS_STATS)。

希望 DotRas 将为您提供一种在 C# 中访问该函数及其返回的所有数据的简单方法。

首先，你必须找到这个网络接口设备。您可以使用GetAllNetworkInterfaces()来完成此操作。现在，您已经有了一个网络接口。之后，网络接口发送此方法。

static void getCurrentNicLifeTime(NetworkInterface adapter)
    {
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();

        UnicastIPAddressInformationCollection uniCast = adapterProperties.UnicastAddresses;

        if (uniCast.Count > 0)
        {
            foreach (UnicastIPAddressInformation uni in uniCast)
            {
                DateTime when;
                when = DateTime.UtcNow + TimeSpan.FromSeconds(uni.AddressValidLifetime) - TimeSpan.FromSeconds(864000);
                when = when.ToLocalTime();

                Console.WriteLine(DateTime.UtcNow.ToLocalTime() - when);
            }
        }
    }

您还可以检查这个例子。

First of all, you must find this network interface device. You can do this by using the GetAllNetworkInterfaces().Now, you have a network interface. After, the network interface send this methot.

static void getCurrentNicLifeTime(NetworkInterface adapter)
    {
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();

        UnicastIPAddressInformationCollection uniCast = adapterProperties.UnicastAddresses;

        if (uniCast.Count > 0)
        {
            foreach (UnicastIPAddressInformation uni in uniCast)
            {
                DateTime when;
                when = DateTime.UtcNow + TimeSpan.FromSeconds(uni.AddressValidLifetime) - TimeSpan.FromSeconds(864000);
                when = when.ToLocalTime();

                Console.WriteLine(DateTime.UtcNow.ToLocalTime() - when);
            }
        }
    }

You can also examine this example.

首先添加来自 Network List Manager 1.0 类型库的引用。在这里您可以根据时区更改日期

    var manager = new NetworkListManager();
    var connectedNetworks = manager.GetNetworks(NLM_ENUM_NETWORK.NLM_ENUM_NETWORK_CONNECTED).Cast<INetwork>();
    foreach (var network in connectedNetworks)
    {
        if (network.IsConnected)
        {
          network.GetTimeCreatedAndConnected(out uint _, out uint _, out uint 
          pdwLowDateTimeConnected, out uint pdwHighDateTimeConnected);

          DateTime networkConnectedTime = DateTime.FromFileTimeUtc((long) 
        (((ulong)pdwHighDateTimeConnected << 32) | pdwLowDateTimeConnected));

        TimeSpan diff = DateTime.Now.Subtract(networkConnectedTime);

        Console.WriteLine("Name: " + network.GetName() + " NetworkDuration : {0} day(s) {1}:{2}:{3}", diff.Days, diff.Hours, diff.Minutes, diff.Seconds);
             }
 }

First Add reference from Network List Manager 1.0 Type Library. Here you can change date as per timezone

    var manager = new NetworkListManager();
    var connectedNetworks = manager.GetNetworks(NLM_ENUM_NETWORK.NLM_ENUM_NETWORK_CONNECTED).Cast<INetwork>();
    foreach (var network in connectedNetworks)
    {
        if (network.IsConnected)
        {
          network.GetTimeCreatedAndConnected(out uint _, out uint _, out uint 
          pdwLowDateTimeConnected, out uint pdwHighDateTimeConnected);

          DateTime networkConnectedTime = DateTime.FromFileTimeUtc((long) 
        (((ulong)pdwHighDateTimeConnected << 32) | pdwLowDateTimeConnected));

        TimeSpan diff = DateTime.Now.Subtract(networkConnectedTime);

        Console.WriteLine("Name: " + network.GetName() + " NetworkDuration : {0} day(s) {1}:{2}:{3}", diff.Days, diff.Hours, diff.Minutes, diff.Seconds);
             }
 }
