仿照网上的一个代码写的，地址找不到了。

将窗体，控件什么的都封装到一个类库里面了，方便以后使用。

界面效果：

窗体模板，主要是实现一个无边框窗体，并添加阴影效果。

?

<Style TargetType="DazzleWPF:DazzleWindow">

    <Setter Property="AllowsTransparency" Value="true"/>

    <Setter Property="Background" Value="Transparent"/>

    <!--<Setter Property="ResizeMode" Value="CanResizeWithGrip"/>-->

    <Setter Property="WindowStyle" Value="None"/>

    <Setter Property="Template">

        <Setter.Value>

            <ControlTemplate TargetType="DazzleWPF:DazzleWindow">

                <Grid Margin="5">

                    <Rectangle Fill="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"    >

                        <Rectangle.Effect>

                            <DropShadowEffect BlurRadius="10" ShadowDepth="0"/>

                        </Rectangle.Effect>

                    </Rectangle>

                    <Border Background="{TemplateBinding Background}"   

                    BorderBrush="{TemplateBinding BorderBrush}"   

                    BorderThickness="{TemplateBinding BorderThickness}"   

                    Padding="{TemplateBinding Margin}"   

                    SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}">

                        <ContentPresenter />

                    </Border>

                </Grid>

            </ControlTemplate>

        </Setter.Value>

    </Setter>

</Style>

　　窗体类，代码也很简单，调用一下类WindowBehaviorHelper 的方法，实现缩放操作的修复，避免最大化覆盖任务栏等。

　　再添加一下鼠标左键按下的拖动支持。

　　就OK了。

?

public class DazzleWindow : Window

{

    public DazzleWindow()

    {

        this.DefaultStyleKey = typeof(DazzleWindow);

 

        //缩放，最大化修复

        WindowBehaviorHelper wh = new WindowBehaviorHelper(this);

        wh.RepairBehavior();

 

        this.MouseLeftButtonDown += new System.Windows.Input.MouseButtonEventHandler(DazzleWindow_MouseLeftButtonDown);

    }

 

    void DazzleWindow_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)

    {

        this.DragMove();

    }

}

　　窗体行为修复，主要代码来了：
