🏗️ 数据结构设计

C#
public partial class Form1 : Form
{
    // 定时器和网络接口
    private Timer updateTimer;
    private NetworkInterface selectedInterface;
    private List<NetworkInterface> networkInterfaces;
    
    // 历史数据存储
    private List<double> downloadHistory;
    private List<double> uploadHistory;
    private List<DateTime> timeHistory;
    
    // 基准数据用于计算差值
    private long lastBytesReceived;
    private long lastBytesSent;
    private DateTime lastUpdateTime;
    
    // 数据点控制
    private int maxHistoryPoints = 60; // 保留60个数据点（1分钟历史）
    
    // ScottPlot 图表对象
    private ScottPlot.Plottables.Scatter downloadPlot;
    private ScottPlot.Plottables.Scatter uploadPlot;
}

💡 设计亮点： 使用差值计算法精确测量网络速度，避免累积误差。

🚀 核心功能实现

🌐 网络接口发现与初始化

C#
private void LoadNetworkInterfaces()
{
    // 获取所有活跃的非回环网络接口
    networkInterfaces = NetworkInterface.GetAllNetworkInterfaces()
        .Where(ni => ni.OperationalStatus == OperationalStatus.Up &&
                   ni.NetworkInterfaceType != NetworkInterfaceType.Loopback)
        .ToList();

    comboBoxInterfaces.Items.Clear();
    foreach (var ni in networkInterfaces)
    {
        // 显示友好的接口名称
        comboBoxInterfaces.Items.Add($"{ni.Name} ({ni.NetworkInterfaceType})");
    }

    if (comboBoxInterfaces.Items.Count > 0)
    {
        comboBoxInterfaces.SelectedIndex = 0;
        selectedInterface = networkInterfaces[0];

        // 🔥 关键：初始化基准值，确保第一次计算的准确性
        var stats = selectedInterface.GetIPv4Statistics();
        lastBytesReceived = stats.BytesReceived;
        lastBytesSent = stats.BytesSent;
    }
}

⚠️ 注意事项：

过滤掉回环接口避免干扰
只选择运行状态的接口
初始化基准值是关键步骤

📈 图表初始化与配置

C#
private void SetupChart()
{
    // 清除所有绘图对象
    formsPlot.Plot.Clear();
    formsPlot.Plot.Legend.FontName = "SimSun"; // 中文字体支持

    // 🎨 坐标轴美化
    formsPlot.Plot.Axes.Left.Label.Text = "速度 (KB/s)";
    formsPlot.Plot.Axes.Bottom.Label.Text = "时间";
    formsPlot.Plot.Axes.Left.Label.FontSize = 12;
    formsPlot.Plot.Axes.Bottom.Label.FontSize = 12;
    formsPlot.Plot.Axes.Bottom.Label.FontName = "SimSun";
    formsPlot.Plot.Axes.Left.Label.FontName = "SimSun";

    // 📊 创建下载速度线条
    downloadPlot = formsPlot.Plot.Add.Scatter(new double[0], new double[0]);
    downloadPlot.Color = ScottPlot.Color.FromHtml("#007BFF"); // 专业蓝色
    downloadPlot.LineWidth = 2;
    downloadPlot.MarkerSize = 0; // 不显示数据点，保持线条流畅
    downloadPlot.LegendText = "下载速度";

    // 📤 创建上传速度线条
    uploadPlot = formsPlot.Plot.Add.Scatter(new double[0], new double[0]);
    uploadPlot.Color = ScottPlot.Color.FromHtml("#DC3545"); // 警示红色
    uploadPlot.LineWidth = 2;
    uploadPlot.MarkerSize = 0;
    uploadPlot.LegendText = "上传速度";

    // 显示图例并设置时间轴
    formsPlot.Plot.ShowLegend(Alignment.UpperRight);
    formsPlot.Plot.Axes.DateTimeTicksBottom(); // 时间轴格式化

    formsPlot.Refresh();
}

🎨 设计技巧：

使用专业配色方案提升视觉效果
时间轴自动格式化提升用户体验
图例位置优化避免遮挡数据

⚡ 实时数据更新核心逻辑

C#
private void UpdateTimer_Tick(object sender, EventArgs e)
{
    if (selectedInterface == null) return;

    try
    {
        var stats = selectedInterface.GetIPv4Statistics();
        var currentTime = DateTime.Now;
        var timeSpan = (currentTime - lastUpdateTime).TotalSeconds;

        // 🔥 核心算法：差值法计算实时速度
        if (timeSpan > 0 && lastBytesReceived > 0 && lastBytesSent > 0)
        {
            // 计算速度 (KB/s)
            double downloadSpeed = (stats.BytesReceived - lastBytesReceived) / timeSpan / 1024;
            double uploadSpeed = (stats.BytesSent - lastBytesSent) / timeSpan / 1024;

            // 🛡️ 防御性编程：确保速度不为负数
            downloadSpeed = Math.Max(0, downloadSpeed);
            uploadSpeed = Math.Max(0, uploadSpeed);

            // 更新各个显示组件
            UpdateRealTimeDisplay(downloadSpeed, uploadSpeed, stats);
            UpdateHistory(downloadSpeed, uploadSpeed, currentTime);
            UpdateChart();
        }

        // 更新基准值
        lastBytesReceived = stats.BytesReceived;
        lastBytesSent = stats.BytesSent;
        lastUpdateTime = currentTime;
    }
    catch (Exception ex)
    {
        // 🚨 优雅的错误处理
        labelStatus.Text = $"监控错误: {ex.Message}";
        labelStatus.ForeColor = System.Drawing.Color.Red;
    }
}

💡 算法亮点：

差值除以时间间隔得到精确速度
防御性编程避免异常数据
异常处理保证程序稳定性

            formsPlot.Plot.Remove(uploadPlot);

        // 重新创建图表对象
        downloadPlot = formsPlot.Plot.Add.Scatter(timeArray, downloadArray);
        downloadPlot.Color = ScottPlot.Color.FromHtml("#007BFF");
        downloadPlot.LineWidth = 2;
        downloadPlot.MarkerSize = 0;
        downloadPlot.LegendText = "下载速度";

        uploadPlot = formsPlot.Plot.Add.Scatter(timeArray, uploadArray);
        uploadPlot.Color = ScottPlot.Color.FromHtml("#DC3545");
        uploadPlot.LineWidth = 2;
        uploadPlot.MarkerSize = 0;
        uploadPlot.LegendText = "上传速度";

        formsPlot.Plot.ShowLegend(Alignment.UpperRight);

        // 🎯 智能坐标轴调整
        formsPlot.Plot.Axes.AutoScale();

        // 设置X轴显示最近的时间窗口
        if (timeArray.Length > 0)
        {
            var latestTime = timeArray[timeArray.Length - 1];
            var earliestTime = DateTime.Now.AddSeconds(-maxHistoryPoints).ToOADate();
            formsPlot.Plot.Axes.SetLimitsX(earliestTime, latestTime);
        }

        formsPlot.Refresh();
    }
    catch (Exception ex)
    {
        // 🛡️ 图表更新失败不影响主程序
        System.Diagnostics.Debug.WriteLine($"Chart update error: {ex.Message}");
    }
}

🎯 用户界面交互

C#
private void comboBoxInterfaces_SelectedIndexChanged(object sender, EventArgs e)
{
    if (comboBoxInterfaces.SelectedIndex >= 0)
    {
        selectedInterface = networkInterfaces[comboBoxInterfaces.SelectedIndex];

        // 🔄 重置统计基准
        var stats = selectedInterface.GetIPv4Statistics();
        lastBytesReceived = stats.BytesReceived;
        lastBytesSent = stats.BytesSent;
        lastUpdateTime = DateTime.Now;

        // 清空历史数据重新开始
        downloadHistory.Clear();
        uploadHistory.Clear();
        timeHistory.Clear();

        // 重新初始化图表
        formsPlot.Plot.Clear();
        SetupChart();

        labelStatus.Text = $"已切换到: {selectedInterface.Name}";
        labelStatus.ForeColor = System.Drawing.Color.Blue;
    }
}

private void buttonStartStop_Click(object sender, EventArgs e)
{
