如何在WP7应用程序的代码隐藏文件中为silverlight中的按钮设置背景图像

发布于 2024-12-08 18:21:51 字数 325 浏览 0 评论 0原文

我想知道如何在代码中而不是在 xaml 中动态地将图像添加到按钮。有人建议按照以下方式继续

ImageBrush brush = new ImageBrush();
brush.ImageSource = new BitmapImage(new Uri(@"Images/myImage.png", UriKind.Relative)); 
AlphabetButton.Background = brush;

，但智能感知未检测到 BitmapImage，尽管我可以找到 BitConvertor 和 Bitmapcache。如果这不是方法，我还能如何设置背景图像

I would like tho know how to add an image to a button dynamically in the code rather than in xaml. Someone had suggested to proceed the following way

ImageBrush brush = new ImageBrush();
brush.ImageSource = new BitmapImage(new Uri(@"Images/myImage.png", UriKind.Relative)); 
AlphabetButton.Background = brush;

but BitmapImage is not detected by the intellisense though i can find BitConvertor and Bitmapcache.
If this is not the method, how else would i set the background images

代码：

ImageBrush background = new ImageBrush();
background.ImageSource = new System.Windows.Media.Imaging.BitmapImage(new Uri(@"SplashScreenImage.jpg", UriKind.Relative));
Button1.Background = background;

按预期工作。 BitmapImage 位于 System.Windows.dll 中，它应该已经在您的 WP7 项目中。

The code:

ImageBrush background = new ImageBrush();
background.ImageSource = new System.Windows.Media.Imaging.BitmapImage(new Uri(@"SplashScreenImage.jpg", UriKind.Relative));
Button1.Background = background;

Works as expected. BitmapImage is in System.Windows.dll which should already be in your WP7 project.
