Question

我想从代码中添加背景颜色和9前景图像到9个按钮。我希望改变C＃中的图像而不是WPF / xaml中的图像。背景颜色可以正常使用：

button1.Background.SetValue(SolidColorBrush.ColorProperty, Windows.UI.Colors.Red);

Windows窗体使用以下方法提供了一个简单的解决方案：

pictureBox1.Image = Properties.Resources.P1; // this does not work for UWP

到目前为止，我所尝试的内容最终出现在错误消息中：我已将P1.png的Build Action属性从Content更改为PRIResource，但没有成功。

string url = "../../Images/P1.png";
//string url = "PW.png";
image1.Source = new BitmapImage(new Uri(url, UriKind.Relative)); //.Uri cannot be converted into a Windows.Foundation.Uri.
//image1.Source = new BitmapImage(new Uri(url, UriKind.Absolute)); //format of url could not be determined

<Button x:Name="button1" Content="Button"  Grid.Column="0" Grid.Row="0"  
                Tag="1" Background="Gray" Padding="0" UseLayoutRounding="False"  
                HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Click="button1_Click">
    <Button.Foreground>
        <ImageBrush Stretch="Fill" ImageSource="P1.PNG"/>
    </Button.Foreground>
</Button>

解决方案：使用VS2015，UWP和Windows 8.1将图像插入C＃中的Button：

将图像添加到按钮的正面。例如Name = button1和imageX。确保将* .png的“Build Action”属性设置为Content。

enter code hereImageBrush imageBrush = new ImageBrush();
        imageBrush.ImageSource = new BitmapImage(new Uri("ms-appx:///Images/PW.PNG"));
        button1.Background = imageBrush;
 BitmapImage bitImage = new BitmapImage();
        bitImage.UriSource = new Uri("ms-appx:///Images/PW.PNG");
        imageX.Source = bitImage;
