推荐答案

自相机以来app将图像存储在预定义的位置（如果您有存储卡，则为2），您可以使用FileSystemWatcher（OpenNETCF SDF）类来监视这些位置。存在一个小问题，即能够判断图像是由相机产生的，还是仅从其他地方复制到设备中。您可以通过读取图像标题属性（OpenNETCF.Drawing.Imaging）并确保刚刚创建图像来解决它。

Since the camera app stores the images in the predefined location (or 2 if you have a storage card), you can use FileSystemWatcher (OpenNETCF SDF) class to monitor these locations. There is a minor issue of being able to tell if the image has been produced by the camera, or just copied to the device from elsewhere. You can resolve it by reading the image header properties (OpenNETCF.Drawing.Imaging) and making sure image has been created just now.
