WPF中的图标闪烁功能

代码示例

using System.Runtime.InteropServices;
using System.Windows.Interop;
using System.Windows;namespace AutoFeed.ViewModel
{// 用于存储窗口闪烁信息的结构体[StructLayout(LayoutKind.Sequential)]public struct FLASHWINFO{public uint cbSize;         // 结构体大小public IntPtr hwnd;         // 窗口句柄public uint dwFlags;        // 闪烁标志public uint uCount;         // 闪烁次数public uint dwTimeout;      // 闪烁间隔时间}public class API{// 同时闪烁窗口标题和任务栏按钮public const uint FLASHW_ALL = 3;// 持续闪烁直到窗口激活public const uint FLASHW_TIMERNOFG = 12;// 调用Windows API实现窗口闪烁[DllImport("user32.dll")][return: MarshalAs(2)]public static extern bool FlashWindowEx(ref FLASHWINFO pwfi);// 开始闪烁窗口public static void FlashWindow(Window window){// 获取窗口句柄WindowInteropHelper h = new WindowInteropHelper(window);// 初始化闪烁信息FLASHWINFO info = new FLASHWINFO{hwnd = h.Handle,dwFlags = FLASHW_ALL | FLASHW_TIMERNOFG, // 同时闪烁标题和任务栏，直到窗口激活uCount = uint.MaxValue,  // 无限次数dwTimeout = 0            // 使用默认间隔};// 设置结构体大小info.cbSize = Convert.ToUInt32(Marshal.SizeOf(info));// 启动闪烁FlashWindowEx(ref info);}// 停止闪烁窗口public static void StopFlashingWindow(Window window){WindowInteropHelper h = new WindowInteropHelper(window);FLASHWINFO info = new FLASHWINFO{hwnd = h.Handle,dwFlags = 0,             // 停止闪烁的标志uCount = uint.MaxValue,dwTimeout = 0};info.cbSize = Convert.ToUInt32(Marshal.SizeOf(info));// 停止闪烁FlashWindowEx(ref info);}}}
