wp7给图片和按钮添加背景图片

为图片或按钮自定义图片

 工程目录下新建文件夹Images，将图片文件复制到Images文件夹里，本文以image1为例

1.在xaml里加背景图片

    image图片： <Stretch="Fill" Source="Images/image1.png"  Name="image"/>

    Button背景图片：<Button Name="button1" >
            <Button.Background>
                <ImageBrush ImageSource="/Images/image1.png" />
            </Button.Background>
        </Button>

 

2.在程序代码里添加

自定义两个方法：

　　    public void changeBack(Image image, String url)
        {
            image.Source = new BitmapImage(new Uri(url, UriKind.Relative));
        }

 　　public void changeBack(Button btn,String url)
        {
            ImageBrush imageBrush = new ImageBrush();
            imageBrush.ImageSource = new BitmapImage(new Uri(url, UriKind.Relative));
            btn.Background = imageBrush;
        }

     image加背景图片：changeBack(image,"Images/image1.png")

     button加背景图片:changeBack(button,,"Images/image1.png");
