请参阅下面的代码，如何将 IsolatedStorageFileStream-obj 转移到 IInputStream-obj？谢谢！

using(IsolatedStorageFileStream stream = 
   IsolatedStorageFile.GetUserStoreForApplication().OpenFile(".."), FileMode.Open))

在 WP8 上：

using System.IO;

using(IsolatedStorageFileStream stream = IsolatedStorageFile.GetUserStoreForApplication().OpenFile("..", FileMode.Open))
    await storedContact.SetDisplayPictureAsync(stream.AsInputStream());
