03-设置登录窗体的背景图片和最小化和关闭按钮

我们设计或者下载一张图片 用来作为登录框的背景颜色。
我们这些都是参考QQ的界面的。
然后我们再项目中添加一个文件夹Images 然后把图片拷贝进去
然后添加如下代码

<Window.Background>
    <ImageBrush ImageSource="Images/background.png"/>
</Window.Background>Code language: HTML, XML (xml)

添加布局增加最小化和关闭按钮
使用DockPanel来布局

<DockPanel LastChildFill="False">
    <DockPanel Background="Transparent" DockPanel.Dock="Top" Height="25" LastChildFill="False">
        <TextBlock Text="QQ登录"  Foreground="White"  FontSize="12" Padding="5" DockPanel.Dock="Left"/>
        <StackPanel DockPanel.Dock="Right" Orientation="Horizontal" Background="Transparent" HorizontalAlignment="Right">
            <Button Content=" - " Foreground="White" Background="Transparent" BorderThickness="0" Click="Button_Click_1" Margin="0,5,15,2"></Button>
            <Button Content=" x " Foreground="White" Background="Transparent" BorderThickness="0" Click="Button_Click" Margin="0,5,5,2"></Button>
        </StackPanel>
    </DockPanel>
</DockPanel>Code language: HTML, XML (xml)

private void Button_Click_1(object sender, RoutedEventArgs e)
{
    this.WindowState = WindowState.Minimized;
}
