如何以编程方式设置图像源

Question

当Image的Source属性按以下方式设置时,图片取自/Images/down.png.

我如何以编程方式执行相同的操作？

<Image x:Name="myImg" Source="/MyProject;component/Images/down.png" />

以下操作无效,因为Image.Source属性不是字符串类型.

myImg.Source = "/MyProject;component/Images/down.png"; 

Answer 1

试试这个:

BitmapImage image = new BitmapImage(new Uri("/MyProject;component/Images/down.png", UriKind.Relative));

Answer 2

myImg.Source = new BitmapImage(new Uri(@"component/Images/down.png", UriKind.RelativeOrAbsolute)); 

不要忘记将Build Action设置为"Content",将Copy to output目录设置为"Always".

Answer 3

尝试以这种方式分配图像：

imgFavorito.Source = new BitmapImage(new Uri(base.BaseUri, @"/Assets/favorited.png"));
