如何在两个窗口之间的Wpf应用程序中维护会话？

我认为您需要在窗口上检查空闲时间

在Windows加载事件上

 private static DispatcherTimer idleTimer;
 private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            idleTimer = new DispatcherTimer();
            idleTimer.Interval = TimeSpan.FromSeconds(5);
            idleTimer.Tick += this.OnTimerTick;
            idleTimer.Start();
        }

计时器滴答事件

private void OnTimerTick(object sender, EventArgs e)
{
    uint idleTime = this.GetIdleTime();
    if (idleTime > 5000)
    {
        this.Close();
    }
}

空闲时间助手方法

[DllImport("User32.dll")]
private static extern bool GetLastInputInfo(ref LASTINPUTINFO dummy);


private uint GetIdleTime()
{
    LASTINPUTINFO lastUserAction = new LASTINPUTINFO();
    lastUserAction.CbSize = (uint)System.Runtime.InteropServices.Marshal.SizeOf(lastUserAction);
    GetLastInputInfo(ref lastUserAction);
    return (uint)Environment.TickCount - lastUserAction.DwTime;
}   

internal struct LASTINPUTINFO
{        
    public uint CbSize;   
    public uint DwTime;   

}
