需要添加引用命名空间
using System.IO;
using System.IO.IsolatedStorage;
1.将图片保存到独立存储空间
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
if (myIsolatedStorage.FileExists(App.fileName))
{
myIsolatedStorage.DeleteFile(App.fileName);
}
using(IsolatedStorageFileStream fileStream = myIsolatedStorage.CreateFile(App.fileName))
{
BitmapImage bitmap = new BitmapImage();
bitmap.SetSource(stream);
WriteableBitmap wb = new WriteableBitmap(bitmap);
// Encode WriteableBitmap object to a JPEG stream.
wb.SaveJpeg(fileStream, wb.PixelWidth, wb.PixelHeight, , );
}
}
}
2.从独立存储空间中获取图片
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
if (myIsolatedStorage.FileExists(fileName))
{
using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile(fileName, FileMode.Open, FileAccess.Read))
{
BitmapImage bmp = new BitmapImage();
bmp.SetSource(fileStream);
};
}
}
