C# 自定义按钮，单击后更改图像

嗨，我有那种按钮：

XAML：

---

当我点击按钮图像消失时，我尝试了其他几种方法，但我做不到。我搜索了这个论坛，但没有找到任何能真正帮助我的东西。

您还没有设置

ContentPresenter

Content

属性。

您需要使用

UriKind.Absolute

作为图像路径

  BitmapImage bmi = 
      new BitmapImage(new Uri("C:\\Users\\Daniel\\Desktop\\WPF\\Paint\\skew2.png",
      UriKind.Absolute));
  bbb.Source = bmi ;

XAML

或C#

或者根本就不要设置任何类型。

private void Button_Click(object sender, RoutedEventArgs e)
{
    BitmapImage bmi = new BitmapImage(new Uri("C:\\Users\\Daniel\\Desktop\\WPF\\Paint\\skew2.png", UriKind.Relative));
    bbb.Source = bmi ;
}

  BitmapImage bmi = 
      new BitmapImage(new Uri("C:\\Users\\Daniel\\Desktop\\WPF\\Paint\\skew2.png",
      UriKind.Absolute));
  bbb.Source = bmi ;

        <Button x:Name="button" Content="Button1" HorizontalAlignment="Left" Margin="400,20,0,0" VerticalAlignment="Top" RenderTransformOrigin="-1.258,-5" Click="Button_Click" Height="80" Width="80"/>

    private void Button1_Click(object sender, RoutedEventArgs e)
    {
        button1.Background = new ImageBrush { ImageSource = new BitmapImage(new Uri("ms-appx:/Images/timerg.png", UriKind.RelativeOrAbsolute)) };

    }

    private void Button1_Click(object sender, RoutedEventArgs e)
    {
            BitmapImage bmp = new BitmapImage();
            Uri u = new Uri("ms-appx:/Images/timer.png", UriKind.RelativeOrAbsolute);
            bmp.UriSource = u;
            // NOTE: change starts here
            Image i = new Image();
            i.Source = bmp;
            button1.Content = i;
    }
