Question

每次打开新窗口时，我都会注意到性能下降。当我打开一个新窗口时，我使用它：

@media only screen and (max-width: 1267px) {  /* 10 items */
inner-container {width: 1024px;}
}

@media only screen and (max-width: 1167px) {  /* 9 items */
inner-container {width: 924px;}
}

@media only screen and (max-width: 1067px) {  /* 8 items */
inner-container {width: 824px;}
}

@media only screen and (max-width: 967px) {  /* 7 items */
inner-container {width: 724px;}
}

@media only screen and (max-width: 867px) {  /* 6 items */
inner-container {width: 624px;}
}

@media only screen and (max-width: 767px) {  /* 5 items */
inner-container {width: 524px;}
}

这会导致参考/性能下降，还是我需要深入了解这个应用程序？

编辑：是一个可怕的CanExecute，它正在轮询数据库。

我遇到了同样的问题并通过在新线程中创建新窗口来解决它！这是一个例子：

 Thread windowThread = new Thread(new ThreadStart(() =>
        {
            MyWindow NSWindow = new MyWindow();

            // When the window closes, shut down the dispatcher
            NSWindow.Closed += (s, e) =>
            Dispatcher.CurrentDispatcher.BeginInvokeShutdown(DispatcherPriority.Background);
            NSWindow.Show();
            // Start the Dispatcher Processing
            System.Windows.Threading.Dispatcher.Run();
        }));

        windowThread.SetApartmentState(ApartmentState.STA);
        // Make the thread a background thread
        windowThread.IsBackground = true;
        // Start the thread
        windowThread.Start();

打开和关闭窗口后，WPF应用程序变慢
