如何在Windows Phone 8中使用StoredContact.SetDisplayPictureAsync（IInputStream流）？

Question

請參閱我的代碼，我如何將IsolatedStorageFileStream-obj轉換爲IInputStream-obj？謝謝！

using(IsolatedStorageFileStream stream = 
    IsolatedStorageFile.GetUserStoreForApplication().OpenFile(".."), FileMode.Open)) 
{ 
    await storedContact.SetDisplayPictureAsync(stream); // compile error 
}

在WP8：

using System.IO; 

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