WPF:最小化系统.Windows.窗口的状态

Question

我如何知道System.Windows.Window在最小化之前是处于WindowState.Normal还是WindowState.Maximized？

Answer 1

除非您自己跟踪以前的状态，否则您不会这样做：

private WindowState _previousState = WindowState.Normal;
private void MainWindow_StateChanged(object sender, EventArgs e)
{
if (WindowState == WindowState.Minimized)
{
if (_previousState == WindowState.Maximized)
{
MessageBox.Show("Window was in maximized state before being minimized");
}
else
{
MessageBox.Show("Window was in normal state before being minimized");
}
}
_previousState = WindowState;
}

恐怕没有可用的"PreviousWindowState"属性。
