🖥️ 显示器管理

DisplayMonitor 使用

using ASW.Wpf;

// 获取所有显示器信息
var monitors = DisplayMonitor.All;
foreach (var monitor in monitors) {
    Console.WriteLine($"显示器: {monitor.DeviceName}");
    Console.WriteLine($"分辨率: {monitor.WorkingArea.Width}x{monitor.WorkingArea.Height}");
    Console.WriteLine($"是否主显示器: {monitor.IsPrimary}");
    Console.WriteLine($"DPI: {monitor.DpiX}x{monitor.DpiY}");
}

// 获取主显示器
var primaryMonitor = DisplayMonitor.Primary;
Console.WriteLine($"主显示器分辨率: {primaryMonitor.WorkingArea.Width}x{primaryMonitor.WorkingArea.Height}");

// 获取窗口所在的显示器
var windowMonitor = DisplayMonitor.GetByWindow(myWindow);
Console.WriteLine($"窗口在显示器: {windowMonitor.DeviceName}");

// 刷新显示器信息
DisplayMonitor.Refresh();

// 截图功能
var result = primaryMonitor.Capture("screenshot.png");
if (result.State) {
    Console.WriteLine("截图成功");
} else {
    Console.WriteLine($"截图失败: {result.Message}");
}

// 截取所有显示器
var allScreenResult = DisplayMonitor.CaptureAll("all_screens.png");

多显示器应用示例

public class MultiMonitorManager
{
    public void DistributeWindows(List<Window> windows)
    {
        var monitors = DisplayMonitor.All;
        
        for (int i = 0; i < windows.Count; i++) {
            var monitor = monitors[i % monitors.Length]; // 循环分配
            var window = windows[i];
            
            // 设置窗口大小为显示器工作区的80%
            window.Width = monitor.WorkingArea.Width * 0.8;
            window.Height = monitor.WorkingArea.Height * 0.8;
            
            // 手动居中显示（因为没有CenterWindowOnMonitor方法）
            window.Left = monitor.WorkingArea.X + (monitor.WorkingArea.Width - window.Width) / 2;
            window.Top = monitor.WorkingArea.Y + (monitor.WorkingArea.Height - window.Height) / 2;
            
            window.Show();
        }
    }
    
    public void CreateMonitorConfigWindow()
    {
        var configWindow = new Window {
            Title = "显示器配置",
            Width = 800,
            Height = 600
        };
        
        var stackPanel = new StackPanel();
        var monitors = DisplayMonitor.All;
        
        foreach (var monitor in monitors) {
            var groupBox = new GroupBox {
                Header = $"显示器 {monitor.DeviceName}"
            };
            
            var infoPanel = new StackPanel();
            infoPanel.Children.Add(new TextBlock { 
                Text = $"分辨率: {monitor.Bounds.Width}x{monitor.Bounds.Height}" 
            });
            infoPanel.Children.Add(new TextBlock { 
                Text = $"工作区: {monitor.WorkingArea.Width}x{monitor.WorkingArea.Height}" 
            });
            infoPanel.Children.Add(new TextBlock { 
                Text = $"DPI: {monitor.DpiX}x{monitor.DpiY}" 
            });
            infoPanel.Children.Add(new TextBlock { 
                Text = $"主显示器: {(monitor.IsPrimary ? "是" : "否")}" 
            });
            
            groupBox.Content = infoPanel;
            stackPanel.Children.Add(groupBox);
        }
        
        configWindow.Content = new ScrollViewer { Content = stackPanel };
        configWindow.Show();
    }
}

🎨 视觉效果

🔧 实用工具

WpfUtils工具类

using ASW.Wpf;

// 线程安全的UI操作
WpfUtils.SafeRun(() => {
    myTextBlock.Text = "更新文本";
    myProgressBar.Value = 50;
});

// 异步UI操作
var result = await WpfUtils.SafeExecuteAsync(() => {
    return myComboBox.SelectedItem.ToString();
});

// 检查管理员权限
if (WpfUtils.IsRunAsAdmin) {
    // 以管理员身份运行的特殊操作
    EnableAdminFeatures();
} else {
    // 普通用户操作
    ShowLimitedFeatures();
}

绑定代理使用

<Window>
    <Window.Resources>
        <asw:BindingProxy x:Key="DataContextProxy" Data="{Binding}" />
    </Window.Resources>
    
    <DataGrid ItemsSource="{Binding Items}">
        <DataGrid.Columns>
            <DataGridTemplateColumn Header="操作">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        
                        <Button Content="删除" 
                                Command="{Binding Data.DeleteCommand, 
                                        Source={StaticResource DataContextProxy}}"
                                CommandParameter="{Binding}" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>
</Window>

UI定时器组

using ASW.Wpf;

// 创建UI定时器组
var uiTimerGroup = new UITimerGroup();

// 延迟更新UI
uiTimerGroup.Delay(TimeSpan.FromSeconds(2), () => {
    statusLabel.Content = "操作完成";
    progressBar.Visibility = Visibility.Hidden;
});

// 周期性更新UI
uiTimerGroup.Interval(TimeSpan.FromSeconds(1), () => {
    timeLabel.Content = DateTime.Now.ToString("HH:mm:ss");
});

// 条件性定时器
uiTimerGroup.While(
    condition: () => IsProcessing,
    interval: TimeSpan.FromMilliseconds(100),
    action: () => progressBar.Value = GetProcessProgress()
);

// 清理定时器
uiTimerGroup.Clear();

Windows消息处理

using ASW.Wpf;

public partial class MainWindow : Window
{
    private WinMessageHandler messageHandler;
    
    public MainWindow()
    {
        InitializeComponent();
        
        // 创建消息处理器
        messageHandler = new WinMessageHandler(this);
        
        // 注册消息处理
        messageHandler.AddMessageHandler(0x0312, OnHotKeyPressed); // WM_HOTKEY
        messageHandler.AddMessageHandler(0x0219, OnDeviceChange);  // WM_DEVICECHANGE
    }
    
    private IntPtr OnHotKeyPressed(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam)
    {
        int hotkeyId = wParam.ToInt32();
        Console.WriteLine($"热键被按下: {hotkeyId}");
        
        // 处理热键逻辑
        HandleHotKey(hotkeyId);
        
        return IntPtr.Zero;
    }
    
    private IntPtr OnDeviceChange(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam)
    {
        // 处理设备变化
        Console.WriteLine("设备发生变化");
        RefreshDeviceList();
        
        return IntPtr.Zero;
    }
}

常见问题

Q: 行为不生效？

xmlns:behaviors="clr-namespace:ASW.Wpf.Behaviors;assembly=ASW.Wpf"


<TextBox>
    <behaviors:TextBoxBehavior.SelectAllOnFocus>
        <behaviors:SelectAllOnFocusBehavior />
    </behaviors:TextBoxBehavior.SelectAllOnFocus>
</TextBox>

Q: 绑定失败？

<UserControl.Resources>
    <asw:BindingProxy x:Key="Proxy" Data="{Binding}" />
</UserControl.Resources>


<Button Command="{Binding Data.MyCommand, Source={StaticResource Proxy}}" />

Q: 显示器信息获取失败？

try {
    var monitors = DisplayMonitor.GetAllDisplayMonitors();
    if (monitors.Count == 0) {
        Console.WriteLine("无法获取显示器信息，可能需要管理员权限");
    }
} catch (Exception ex) {
    Console.WriteLine($"获取显示器信息失败: {ex.Message}");
}

💡 最佳实践

性能优化

// 1. 缓存转换器实例
public static class Converters
{
    public static readonly BoolToVisibilityConverter BoolToVisibility = new();
    public static readonly StringToUpperConverter StringToUpper = new();
}

// 2. 使用静态资源
<Window.Resources>
    <converters:BoolToVisibilityConverter x:Key="BoolToVisibilityConverter" />
</Window.Resources>

// 3. 避免在循环中创建行为
// 使用样式统一应用行为
<Style TargetType="TextBox">
    <Setter Property="behaviors:TextBoxBehavior.SelectAllOnFocus">
        <Setter.Value>
            <behaviors:SelectAllOnFocusBehavior />
        </Setter.Value>
    </Setter>
</Style>

代码组织

// 1. 创建自定义行为基类
public abstract class CustomBehaviorBase<T> : Behavior<T> where T : DependencyObject
{
    protected override void OnAttached()
    {
        base.OnAttached();
        Subscribe();
    }
    
    protected override void OnDetaching()
    {
        Unsubscribe();
        base.OnDetaching();
    }
    
    protected abstract void Subscribe();
    protected abstract void Unsubscribe();
}

// 2. 实现自定义行为
public class CustomValidationBehavior : CustomBehaviorBase<TextBox>
{
    protected override void Subscribe()
    {
        AssociatedObject.TextChanged += OnTextChanged;
    }
    
    protected override void Unsubscribe()
    {
        AssociatedObject.TextChanged -= OnTextChanged;
    }
    
    private void OnTextChanged(object sender, TextChangedEventArgs e)
    {
        // 验证逻辑
    }
}
