Windows phone 8 无法序列化Windows Phone 8 ImageSource共享图像时出错

我正在尝试分享一个图像。我得到了一个图片对象，正在从中获取路径。调用ShareMediaTask时，它会抛出以下错误：

无法序列化System.Windows.Media.ImageSource

我仍然可以共享图像，但从共享返回时应用程序崩溃

这是我的密码：

        PictureModel picture = Singleton.Instance.BearPicture.Model.Images.Where(PictureModel => PictureModel.Bmp.UriSource == (Image_View.Source as BitmapImage).UriSource).FirstOrDefault();


        var task = new ShareMediaTask();


        task.FilePath = picture.Picture.GetPath();

        task.Show();

我的PictureModel如下所示：

 public class PictureModel : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private string _uri;
    public string Uri
    {
        get { return _uri; }
        set
        {
            if (value != _uri)
            {
                _uri = value;
                NotifyPropertyChanged("Uri");
            }
        }
    }

    private string _relativePath;
    public string RelativePath
    {
        get { return _relativePath; }
        set
        {
            if (_relativePath != value)
            {
                _relativePath = value;
                NotifyPropertyChanged("RelativePath");
            }
        }
    }

    private BitmapImage _bmp;
    public BitmapImage Bmp
    {
        get { return _bmp; }
        set
        {
            if (value != _bmp)
            {
                _bmp = value;
                NotifyPropertyChanged("Bmp");
            }
        }
    }

    private Picture _picture;
    public Picture Picture
    {
        get { return _picture; }
        set
        {
            if (value != _picture)
            {
                _picture = value;
                NotifyPropertyChanged("Picture");
            }
        }
    }

    private void NotifyPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }

    }

}

  myFileStream = myStore.OpenFile(fileName, FileMode.Open, FileAccess.Read);
            MediaLibrary library = new MediaLibrary();
            Picture pic = library.SavePicture(fileName, myFileStream);

这个错误是从哪里来的？我只得到我的图像对象的来源，但我没有用它做任何其他事情。我的图片也保存在媒体库中，如下所示：

 public class PictureModel : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private string _uri;
    public string Uri
    {
        get { return _uri; }
        set
        {
            if (value != _uri)
            {
                _uri = value;
                NotifyPropertyChanged("Uri");
            }
        }
    }

    private string _relativePath;
    public string RelativePath
    {
        get { return _relativePath; }
        set
        {
            if (_relativePath != value)
            {
                _relativePath = value;
                NotifyPropertyChanged("RelativePath");
            }
        }
    }

    private BitmapImage _bmp;
    public BitmapImage Bmp
    {
        get { return _bmp; }
        set
        {
            if (value != _bmp)
            {
                _bmp = value;
                NotifyPropertyChanged("Bmp");
            }
        }
    }

    private Picture _picture;
    public Picture Picture
    {
        get { return _picture; }
        set
        {
            if (value != _picture)
            {
                _picture = value;
                NotifyPropertyChanged("Picture");
            }
        }
    }

    private void NotifyPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }

    }

}

  myFileStream = myStore.OpenFile(fileName, FileMode.Open, FileAccess.Read);
            MediaLibrary library = new MediaLibrary();
            Picture pic = library.SavePicture(fileName, myFileStream);

在Appstart上，我搜索我的savedpicture文件夹，以获取图片对象，然后将其保存在我的PictureModel中

感谢您的帮助。 提前谢谢。 robidd

这可能有帮助：。请参阅KooKiz的评论

“相同的症状，相同的原因。您在某个时间点以电话状态存储了一个图像源（可能是PhoneApplicationService.Current.state或IsolatedStorageSettings.ApplicationSettings）。您必须找到位置！”

显然，我们可以间接导致这种错误。我有一个类似的问题，我找到了答案，也找到了你自己的问题

希望能有帮助。 干杯
