最大化WPF不会更新宽度？

Width在最大化窗口时,屏幕的属性似乎不会更新为完全最大化的宽度.如果我调整大小,一切正常,但不是最大化时.

我的代码如下:

private void Window_SizeChanged(object sender, SizeChangedEventArgs e)
{
    UpdateColumns();
}

private void button1_Click(object sender, RoutedEventArgs e)
{
    UpdateColumns();
}

private void UpdateColumns()
{
    ColumnCount = Math.Round(Width/150);
    statusBarItemColumnCount.Content = ColumnCount;
    button1.Content = ColumnCount + " " + Width;
}

private void Window_StateChanged(object sender, EventArgs e)
{
    UpdateColumns();
}

看看ActualWidth,而不是Width.
