编辑：我一直收到未处理的OutOfMemoryException异常，我认为这是因为我保存图像到隔离存储的方式，我认为这是我可以解决问题的地方，如何在保存之前减小图像的大小？(添加了保存图像的代码)
我从隔离存储中打开图像，有时会有超过100个图像，并且我想遍历所有这些图像，但当故事板中加载了大约100到150个图像时，我会出现
我在这一行代码上遇到了异常：
我从隔离存储中打开图像，有时会有超过100个图像，并且我想遍历所有这些图像，但当故事板中加载了大约100到150个图像时，我会出现
OutOfMemory Exception。如何处理此异常？我已经降低了图像的分辨率。如何避免我的应用程序崩溃？我在这一行代码上遇到了异常：
image.SetSource(isStoreTwo.OpenFile(projectFolder + "\\MyImage" + i + ".jpg", FileMode.Open, FileAccess.Read));//images from isolated storage
下面是我的代码：private void OnLoaded(object sender, RoutedEventArgs e)
{
IsolatedStorageFile isStoreTwo = IsolatedStorageFile.GetUserStoreForApplication();
try
{
storyboard = new Storyboard
{
//RepeatBehavior = RepeatBehavior.Forever
};
var animation = new ObjectAnimationUsingKeyFrames();
Storyboard.SetTarget(animation, projectImage);
Storyboard.SetTargetProperty(animation, new PropertyPath("Source"));
storyboard.Children.Add(animation);
for (int i = 1; i <= savedCounter; i++)
{
BitmapImage image = new BitmapImage();
image.SetSource(isStoreTwo.OpenFile(projectFolder + "\\MyImage" + i + ".jpg", FileMode.Open, FileAccess.Read));//images from isolated storage
var keyframe = new DiscreteObjectKeyFrame
{
KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(100 * i)),
Value = image
};
animation.KeyFrames.Add(keyframe);
}
}
catch (OutOfMemoryException exc)
{
//throw;
}
Resources.Add("ProjectStoryBoard", storyboard);
storyboard.Begin();
}
编辑 这是我将图像保存到隔离存储的方法，我认为这里可以解决我的问题，当我将其保存到隔离存储时，如何减小图像的大小？
void cam_CaptureImageAvailable(object sender, Microsoft.Devices.ContentReadyEventArgs e)
{
string fileName = folderName+"\\MyImage" + savedCounter + ".jpg";
try
{
// Save picture to the library camera roll.
//library.SavePictureToCameraRoll(fileName, e.ImageStream);
// Set the position of the stream back to start
e.ImageStream.Seek(0, SeekOrigin.Begin);
// Save picture as JPEG to isolated storage.
using (IsolatedStorageFile isStore = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream targetStream = isStore.OpenFile(fileName, FileMode.Create, FileAccess.Write))
{
// Initialize the buffer for 4KB disk pages.
byte[] readBuffer = new byte[4096];
int bytesRead = -1;
// Copy the image to isolated storage.
while ((bytesRead = e.ImageStream.Read(readBuffer, 0, readBuffer.Length)) > 0)
{
targetStream.Write(readBuffer, 0, bytesRead);
}
}
}
}
finally
{
// Close image stream
e.ImageStream.Close();
}
}
I would appreciate if you could help me thanks.
