WPF不规则窗口和Settings.setting设置示例

<Window x:Class="WpfApplication_Transparency.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
AllowsTransparency="True" WindowStyle="None" Background="Transparent"
MouseLeftButtonDown="Window_MouseLeftButtonDown" Loaded="Window_Loaded"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Rectangle Fill="Yellow">
</Rectangle>

<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="10*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Grid.ColumnSpan="3" x:Name="LabelShow"/>
<Label Content="Input" Grid.Row="1" Grid.Column="0"></Label>
<TextBox Grid.Row="1" Grid.Column="1" x:Name="TextBoxInfo"/>
<Button Grid.Row="1" Click="Button_Click_1" Grid.Column="2" Content="Close and Save"/>
</Grid>
</Grid>
</Window>

}
private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
this.DragMove();
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
if (TextBoxInfo.Text != null)
{
Properties.Settings.Default.Infomation = TextBoxInfo.Text;
Properties.Settings.Default.Save();
}
this.Close();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
LabelShow.Content = Properties.Settings.Default.Infomation;
}
}
}

代码讲解：

在MainWindow.xaml中设置mainwindow的属性如下

AllowsTransparency="True"

WindowStyle="None"

Background="Transparent"

可使用不规则窗口。
