WPF 程序监控硬件设备状态变化的实现方案

以下是一个完整的 C# WPF 程序实现方案，用于监控硬件设备状态变化（基于设备 SDK API）。我们将分步骤实现，包含状态轮询、事件通知、UI 绑定和错误处理。

1. 项目结构设计

HardwareMonitor/
├── Models/               # 数据模型
│   └── DeviceStatus.cs
├── Services/            # 硬件服务层
│   ├── IDeviceService.cs
│   └── DeviceService.cs
├── ViewModels/          # MVVM 视图模型
│   └── MainViewModel.cs
├── Views/               # 用户界面
│   └── MainWindow.xaml
└── App.xaml             # 应用程序入口

2. 实现步骤

(1) 定义设备状态模型

// Models/DeviceStatus.cs
public class DeviceStatus : INotifyPropertyChanged
{
    private bool _isConnected;
    public bool IsConnected
    {
        get => _isConnected;
        set { _isConnected = value; OnPropertyChanged(); }
    }

    private double _temperature;
    public double Temperature
    {
        get => _temperature;
        set { _temperature = value; OnPropertyChanged(); }
    }

    public event PropertyChangedEventHandler? PropertyChanged;
    protected void OnPropertyChanged([CallerMemberName] string? name = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
    }
}

(2) 封装设备 SDK API

// Services/IDeviceService.cs
public interface IDeviceService
{
    DeviceStatus CurrentStatus { get; }
    event EventHandler<DeviceStatus> StatusChanged;
    void StartMonitoring();
    void StopMonitoring();
}

// Services/DeviceService.cs
public class DeviceService : IDeviceService, IDisposable
{
    private readonly Timer _pollingTimer;
    private readonly DeviceSDK _sdk; // 假设这是硬件SDK的类

    public DeviceStatus CurrentStatus { get; } = new DeviceStatus();
    public event EventHandler<DeviceStatus>? StatusChanged;

    public DeviceService()
    {
        _sdk
