Question

关闭窗口时尝试序列化。我收到此运行时错误：

发生了System.NotSupportedException类型的未处理异常   在PresentationFramework.dll
中
附加信息：不支持给定路径的格式。

这发生在两个不同的实例中：

使用退出按钮（右上角）
按 Esc 键关闭窗口。

在每个相应的实例上。没有可用的源代码，在引发错误时突出显示了两个this.Close()（请参阅KeysDown中的Window.xaml.cs方法）。

代码（缩减以适合此查询）：

Window.xaml.cs ：

public partial class MainWindow : Window
{
    public SessionManager SM { get; private set; }

    public MainWindow()
    {
        InitializeComponent();
        //code
    }

    /// <summary>
    /// Registered to MainWindow.KeysDown Event
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="kea"></param>
    private void KeysDown(object sender, KeyEventArgs kea)
    {
        switch (kea.Key)
        {
            case Key.Escape:
                this.Close();
                break;
        }
    }

    private void SaveSession(object sender, CancelEventArgs e)
    {
        SM.SaveSession();
    }
}

SessionManager.cs （我的类变量有问题，所以我没有省略它们）：

[Serializable]
    public class SessionManager : DependencyObject
    {
        [NonSerialized]
        public static readonly DependencyProperty currentSessionProperty =
            DependencyProperty.Register("currentSession", typeof(Session),
            typeof(MainWindow), new FrameworkPropertyMetadata(null));
        [NonSerialized]
        public static readonly DependencyProperty startTimeProperty =
            DependencyProperty.Register("strStartTime", typeof(string),
            typeof(MainWindow), new FrameworkPropertyMetadata(DateTime.Now.ToString()));

        private static string SM_FILE = "SessionManager.bin";

        /// <summary>
        /// Holds a list of all comments made within the session
        /// </summary>
        public List<string> Sessions { get; private set; }
        [NonSerialized]
        private DateTime _dtStartTime;

        public SessionManager()
        {
            //code
        }


        #region Methods

        public void SaveSession()
        {
            if (currentSession.timeEntries.Count != 0)
            {
                currentSession.Save();
            }
            else
            {
                Sessions.Remove(currentSession.Name);
            }

            //Serialize the SessionManager
            IFormatter formatter = new BinaryFormatter();
            Stream stream = new FileStream(SM_FILE, FileMode.Create, FileAccess.Write, FileShare.None);
            formatter.Serialize(stream,this);
            stream.Close();
        }

        public void OpenSession(int index)
        {
            IFormatter formatter = new BinaryFormatter();
            Stream stream = new FileStream(Sessions[index], FileMode.OpenOrCreate, FileAccess.Read, FileShare.None);
            currentSession=(Session)formatter.Deserialize(stream);
            stream.Close();
        }
        #endregion
    }

Session.cs （我的类变量有问题，所以我没有省略它们）：

[Serializable]
public class Session : DependencyObject
{
    [NonSerialized]
    public static readonly DependencyProperty nameProperty =
        DependencyProperty.Register("name", typeof(string),
        typeof(Session), new FrameworkPropertyMetadata(string.Empty));

    [NonSerialized]
    public static readonly DependencyProperty totalTimeProperty =
        DependencyProperty.Register("totalTime", typeof(TimeSpan), typeof(Session),
        new PropertyMetadata(TimeSpan.Zero));

    public Session()
    {
        //code
    }

    public void Save()
    {
        IFormatter formatter = new BinaryFormatter();
        Stream stream= new FileStream(Name,FileMode.Create,FileAccess.Write,FileShare.None);
        formatter.Serialize(stream, this);
        stream.Close();
    }
}
