推荐答案

嗨。如果我是你： 在DataBase中保存我的图像名称并创建一个这样的方法： public static BitmapImage GetBitMapImage（string relativeImage） { string imagePath = string.format（pack：// application：,,, / {0}; component /Images/{1}\",Assembly.GetExecutingAssembly().GetName().Name,relativeImage）; URI uri = new URI（imagePath，UriKind.RelativeOrAbsolute ）; 返回新的BitmapImage（uri）; } imagePath中的图像是一个文件夹在您的应用程序中，所有图像都位于其中。 当您需要图像时。您必须写： Image myImage = new Image（）; myImage.Source = GetBitMapImage（这个地方必须填充你的图像名称保存在DataBase中）; 例如： myImage.source = GetBitMapImage（SaveIcon.png）; 此操作非常有用，因为当您需要加载图像时。 祝你好运 Hi.If i was you: Save the name of my images in DataBase and Create a method like this: public static BitmapImage GetBitMapImage(string relativeImage) { string imagePath=string.format("pack://application:,,,/{0};component/Images/{1}",Assembly.GetExecutingAssembly().GetName().Name,relativeImage); URI uri=new URI(imagePath,UriKind.RelativeOrAbsolute); return new BitmapImage(uri); } "Images" in imagePath is a folder in your application that all of image is located in it. when you need to an image.you must write: Image myImage=new Image(); myImage.Source=GetBitMapImage(this place must populate with your image name that is saved in DataBase); for example : myImage.source=GetBitMapImage("SaveIcon.png"); this acction is useful because when you need your image is loaded. Good Luck
