C#获取本地IP地址和MAC地址使用websocket 向服务器发起在线状态注册

要获取本地IP地址和MAC地址，您可以使用C#的System.Net.NetworkInformation命名空间中的NetworkInterface类。以下是一个示例代码：

using System.Net.NetworkInformation;

// 获取本地IP地址
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
    if (nic.OperationalStatus == OperationalStatus.Up)
    {
        IPInterfaceProperties ipProps = nic.GetIPProperties();

        foreach (var ip in ipProps.UnicastAddresses)
        {
            if (ip.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
            {
                string ipAddress = ip.Address.ToString();
                // 在此处使用WebSocket向服务器发送在线状态注册
            }
        }
    }
}

// 获取本地MAC地址
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
    if (nic.OperationalStatus == OperationalStatus.Up)
    {
        PhysicalAddress mac = nic.GetPhysicalAddress();
        string macAddress = BitConverter.ToString(mac.GetAddressBytes());
        // 在此处使用WebSocket向服务器发送在线状态注册
    }
}

要使用WebSocket向服务器发送在线状态注册，您需要使用C#中的WebSocket类，它位于System.Net.WebSockets命名空间中。以下是一个示例代码：

using System.Net.WebSockets;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

public static async Task SendWebSocketMessage(string message)
{
    using (ClientWebSocket ws = new ClientWebSocket())
    {
        await ws.ConnectAsync(new Uri("ws://your-server-url"), CancellationToken.None);

        byte[] messageBytes = Encoding.UTF8.GetBytes(message);
        ArraySegment<byte> messageSegment = new ArraySegment<byte>(messageBytes);

        await ws.SendAsync(messageSegment, WebSocketMessageType.Text, true, CancellationToken.None);
    }
}

将上述代码与获取本地IP地址和MAC地址的代码结合起来，您可以编写一个方法来向服务器发送在线状态注册：

public static async Task RegisterOnlineStatus()
{
    // 获取本地IP地址
    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
    {
        if (nic.OperationalStatus == OperationalStatus.Up)
        {
            IPInterfaceProperties ipProps = nic.GetIPProperties();

            foreach (var ip in ipProps.UnicastAddresses)
            {
                if (ip.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                {
                    string ipAddress = ip.Address.ToString();

                    // 向服务器发送在线状态注册
                    string message = $"{{\"type\": \"register\", \"ip\": \"{ipAddress}\"}}";
                    await SendWebSocketMessage(message);
                }
            }
        }
    }

    // 获取本地MAC地址
    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
    {
        if (nic.OperationalStatus == OperationalStatus.Up)
        {
            PhysicalAddress mac = nic.GetPhysicalAddress();
            string macAddress = BitConverter.ToString(mac.GetAddressBytes());

            // 向服务器发送在线状态注册
            string message = $"{{\"type\": \"register\", \"mac\": \"{macAddress}\"}}";
            await SendWebSocketMessage(message);
        }
    }
}

请注意，此示例代码仅供参考，并且需要根据您的实际情况进行修改。例如，您需要替换“your-server-url”为您的服务器URL。
