为了实现我想要的效果花费了我很长时间，唉，当初英语不好好学，翻官网翻了半天才找到，分享给刚入门的新手。

 

首先看一张图片示例，我们要模仿的dialog就是长这样的：

【代码】

XAML：

 1 <Grid Background="#3d4ba4">
 2         
 3         <ContentDialog x:Name="termsOfUseContentDialog" 
 4           Background="Transparent" BorderBrush="Transparent"
 5                       
 6            >
 7             <Grid CornerRadius="8" Background="White" Width="284" Height="176">
 8                 <StackPanel Margin="20,20,20,54">
 9                     <Image Source="Assets/moren_hashiqi_thumb.png" Stretch="None"/>
10                     <Grid Height="15"></Grid>
11                     <TextBlock Text="Wow... What is your name?" HorizontalAlignment="Center" VerticalAlignment="Center"/>
12                     <TextBlock Text="Kudou Shinichi,Programmer and " VerticalAlignment="Center" HorizontalAlignment="Center"/>
13                     <TextBlock Text="Detective!" VerticalAlignment="Center" HorizontalAlignment="Center"/>
14                 </StackPanel>
15                 <StackPanel VerticalAlignment="Bottom" Orientation="Horizontal">
16                     <Border Height="44" Width="142" BorderBrush="#efefef" BorderThickness="0,1,0,0">
17                         <TextBlock Text="IKnorite" HorizontalAlignment="Center" VerticalAlignment="Center"/>
18                     </Border>
19                     <Border Height="44" Width="142" BorderBrush="#efefef" BorderThickness="1,1,0,0">
20                         <TextBlock Text="Wait,what?" Foreground="#2d7abb" HorizontalAlignment="Center" VerticalAlignment="Center"/>
21                     </Border>
22                 </StackPanel>
23             </Grid>
24 
25         </ContentDialog>
26            
27 
28             <Grid VerticalAlignment="Bottom">
29                 <Button Click="button_Click" x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="36,35,0,0" VerticalAlignment="Top"/>
30             </Grid>
31 
32 
33        
34     </Grid>
前台XAML代码

后台没什么代码就一个事件监听：

技术分享 
1 private async void button_Click(object sender, RoutedEventArgs e)
2         {
3             //弹出提示框
4             await termsOfUseContentDialog.ShowAsync();
5 
6         }
后台代码

 

【小笔记】

自定义在Page页面的ContentDialog不能这样用：

public MainPage()
        {
            this.InitializeComponent();
            //await termsOfUseContentDialog.ShowAsync();【会报错】

            //test();【报错】
        }

        public async void test()
        {
            //await termsOfUseContentDialog.ShowAsync();【会报错】
        }

但是却可以这样用：

 1  public MainPage()
 2         {
 3             this.InitializeComponent();
 4             test();//ok
 5         }
 6 
 7         public async void test()
 8         {
 9             ContentDialog content_dialog = new ContentDialog()
10             {
11                 Title = "退出",
12                 Content = "KudouShinichi",
13                 PrimaryButtonText = "确定",
14                 SecondaryButtonText = "取消",
15                 FullSizeDesired = false,
16             };
17 
18             content_dialog.PrimaryButtonClick += (_s, _e) => { };
19 
20             await content_dialog.ShowAsync();
21         }
