将 NetworkInterface 适配器传递给组合框的方法

Question

大家好：我如何作为网络接口适配器从我的组合框传递到该方法？获取设备信息

私有字符串 GetDeviceInfo（网络接口适配器）？

我将网络设备填充到我的组合框中：

foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
            {
                cbox1.Items.Add(nic.Name);
            }

我有以下方法&如何传递选定的组合框项目？

我知道如何为 ex:xbox 1.Items[combobox1.SelectedIndex].ToString() 选择项目，但我无法理解如何作为网络适配器传递？

private void cbox1_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
        {
//
}

private string GetDeviceInfo(NetworkInterface adapter)
{
    if (adapter == null)
    {
        return String.Empty;
    }

    IPInterfaceProperties properties = adapter.GetIPProperties();

    StringBuilder infoBuilder = new StringBuilder();

    infoBuilder.Append(adapter.Description + "\n");
    infoBuilder.Append("=================================================\n");
    infoBuilder.AppendFormat(" ID ......................... : {0}\n",
        adapter.Id);
    infoBuilder.AppendFormat(" Name ....................... : {0}\n",
        adapter.Name);
    infoBuilder.AppendFormat(" Interface type ............. : {0}\n",
        adapter.NetworkInterfaceType);
    infoBuilder.AppendFormat(" Physical Address ........... : {0}\n",
               BitConverter.ToString(adapter.GetPhysicalAddress().GetAddressBytes()));
    infoBuilder.AppendFormat(" Operational status ......... : {0}\n",
        adapter.OperationalStatus);
    infoBuilder.AppendFormat(" Speed ...................... : {0} Mb/s\n",
        adapter.Speed / 1000000);

    string versions = String.Empty;

    // Create a display string for the supported IP versions.
    if (adapter.Supports(NetworkInterfaceComponent.IPv4))
    {
        versions = "IPv4";
    }
    if (adapter.Supports(NetworkInterfaceComponent.IPv6))
    {
        if (versions.Length > 0)
        {
            versions += " ";
        }
        versions += "IPv6";
    }

    infoBuilder.AppendFormat(" IP version ................. : {0}\n",
        versions);

    infoBuilder.Append(GetIPAddresses(properties));

    // The following information is not useful for loopback adapters.
    if (adapter.NetworkInterfaceType == NetworkInterfaceType.Loopback)
    {
        return infoBuilder.ToString();
    }

    infoBuilder.AppendFormat(" DNS suffix ................. : {0}\n",
        properties.DnsSuffix);

    if (adapter.Supports(NetworkInterfaceComponent.IPv4))
    {
        IPv4InterfaceProperties ipv4 = properties.GetIPv4Properties();

        infoBuilder.AppendFormat(" Index ...................... : {0}\n",
            ipv4.Index);
        infoBuilder.AppendFormat(" MTU ........................ : {0}\n",
            ipv4.Mtu);
        infoBuilder.AppendFormat(" APIPA active ............... : {0}\n",
            ipv4.IsAutomaticPrivateAddressingActive);
        infoBuilder.AppendFormat(" APIPA enabled .............. : {0}\n",
            ipv4.IsAutomaticPrivateAddressingEnabled);
        infoBuilder.AppendFormat(" DHCP enabled ............... : {0}\n",
            ipv4.IsDhcpEnabled);
        infoBuilder.AppendFormat(" Forwarding enabled.......... : {0}\n",
            ipv4.IsForwardingEnabled);
        infoBuilder.AppendFormat(" Uses WINS .................. : {0}\n",
            ipv4.UsesWins);

        if (ipv4.UsesWins)
        {
            IPAddressCollection winsServers = properties.WinsServersAddresses;
            if (winsServers.Count > 0)
            {
                foreach (IPAddress winsServer in winsServers)
                {
                    infoBuilder.AppendFormat(" WINS Server ................ : {0}\n",
                        winsServer);
                }
            }
        }
    }

    if (adapter.Supports(NetworkInterfaceComponent.IPv6))
    {
        IPv6InterfaceProperties ipv6 = properties.GetIPv6Properties();

        infoBuilder.AppendFormat(" Index ...................... : {0}\n",
            ipv6.Index);
        infoBuilder.AppendFormat(" MTU ........................ : {0}\n",
            ipv6.Mtu);
    }

    infoBuilder.AppendFormat(" DNS enabled ................ : {0}\n",
        properties.IsDnsEnabled);
    infoBuilder.AppendFormat(" Dynamically configured DNS . : {0}\n",
        properties.IsDynamicDnsEnabled);
    infoBuilder.AppendFormat(" Receive Only ............... : {0}\n",
        adapter.IsReceiveOnly);
    infoBuilder.AppendFormat(" Multicast .................. : {0}\n",
        adapter.SupportsMulticast);

    return infoBuilder.ToString();
}

不要将网络接口名称添加到组合框项目中，而应直接添加 NetworkInterface 对象。

cbox1.Items.Add(nic);

然后你可以在你的组合框中设置项目模板来修复显示：

<ComboBox.ItemTemplate>
    <DataTemplate>
        <TextBlock Text="{Binding Path=Name}"/>
    </DataTemplate>
</ComboBox.ItemTemplate>

您可以在事件回调中访问您选择的网络接口：

private void cbox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if(e.AddedItems is not null && e.AddedItems.Count > 0 && e.AddedItems[0] is NetworkInterface ni)
    {
       // do something with "ni"
    }
}
