HB方法的一种替代方法是将 Visibility 设置为隐藏，然后将 ShowInTaskbar 设置为错误的.这仍然会创建窗口并让其执行操作.

An alternative to H.B.'s method is just to set the Visibility to hidden and set ShowInTaskbar to false. This still creates the window and lets it do its thing.

<Window x:Class="WpfApplication2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" ShowInTaskbar="False" Visibility="Hidden">
    <Grid>

    </Grid>
</Window>
