C# 如何使用随机颜色更改hub标题的背景和Hubble的图像像素？
我已经准备了一个定制的Hubbile，它有一个图像和文本Bloxk，用于显示所需的图像和文本。我已经将瓷砖的背景颜色硬编码为白色，现在有人可以建议如何使用多种颜色更改瓷砖的背景，也有人可以建议更改图像的颜色吗（也就是说，改变来自服务器的图像像素，它被用作hubbile源）。我一直在使用下面的代码 xaml文件代码C# 如何使用随机颜色更改hub标题的背景和Hubble的图像像素？,c#,windows-phone-8,C#,Windows Phone 8,我已经准备了一个定制的Hubbile，它有一个图像和文本Bloxk，用于显示所需的图像和文本。我已经将瓷砖的背景颜色硬编码为白色，现在有人可以建议如何使用多种颜色更改瓷砖的背景，也有人可以建议更改图像的颜色吗（也就是说，改变来自服务器的图像像素，它被用作hubbile源）。我一直在使用下面的代码 xaml文件代码 <Style x:Key="HomePageTabStyle" TargetType="toolkit:HubTile"> <Setter Pr

谢谢。使用颜色数组，我达到了第一点
Color[] colors=new Color{Colors.Red,Colors.Blue,Colors.White}
Background=new SolidColorBrush(index % colors.Length),
Background=new SolidColorBrush(index % colors.Length),
