Windows Phone开发之图片控件Image及定义URI

[html]
<image grid.column="1"  
               grid.columnspan="3" 
               grid.row="5"  
               grid.rowspan="2"  
               verticalalignment="stretch" 
               horizontalalignment="stretch"               
               name="image1"  
               stretch="uniformtofill"  
               source="/phoneapp4;component/images/jellyfish.jpg"  
               margin="8,0,72,0" /> 
解释：
stretch="uniformtofill" 可以调整大小有拉伸效果
stretch="fill" 任意拉伸调整大小
stretch="uniform" 按照原图比例调整大小
source="/phoneapp4;component/images/jellyfish.jpg" 图片引用路径

后台代码修改图片：
 system.windows.media.imaging.bitmapimage myimage = new bitmapimage();
 myimage.urisource = new uri("/phoneapp4;component/images/tulips.jpg", urikind.relative);
 image1.source = myimage;
