WPF 气泡尖角在左边、下面、右边、上面_.NET_编程开发_程序员俱乐部

由于项目需要，在弄一个气泡提示框，根据网上资料，使用Path可以将气泡画出来，下面是我画出来的。

1、气泡尖角在左边的：

　　

class="code_img_closed" src="/Upload/Images/2014041519/0015B68B3C38AA5B.gif" alt="" />logs_code_hide('e06dcaee-6186-4367-bdcf-b0d4ce78c2e9',event)" src="/Upload/Images/2014041519/2B1B950FA3DF188F.gif" alt="" />

 <Path Stroke="Black" StrokeThickness="0.1" Fill="Yellow" HorizontalAlignment="Right">
            <Path.Data>
                <PathGeometry Figures="
                                      M 10,10 
                                      L 10,10 200,10 
                                      L 200,10 200,100 
                                      L 200,100 10,100
                                      L 10,40 -10,30
                                      L -10,30 10,30
                                      Z"/>
            </Path.Data>
        </Path>

2、气泡尖角在下面的：

　　

adb700bbe02b" class="code_img_closed" src="/Upload/Images/2014041519/0015B68B3C38AA5B.gif" alt="" />

<Path Stroke="Black" StrokeThickness="0.1" Fill="Yellow">
            <Path.Data>
                <PathGeometry Figures="
                                      M 10,10 
                                      L 10,10 200,10

            <Path.Data>
                <PathGeometry Figures="
                                      M 10,10 
                                      L 10,10 200,10

                                      M 10,10 
                                      L 10,10 180,10
