我在WPF中有文本框，当我反序列化保存到磁盘的数据时不会更新。

Question

//我在这里序列化了我的对象

namespace Vdrop
{
    [Serializable]
    public class DCSelections : INotifyPropertyChanged 
     {
        private double _systemVoltage = 125;
        public double SystemVoltage
     {
        get { return _systemVoltage; }
        set
        {
            _systemVoltage = value;
            OnPropertyChanged("SystemVoltage");
        }
    }

//我使用一个事件来进行序列化和反序列化

private void Open_Click(object sender, RoutedEventArgs e)
    {
        IFormatter serializer = new BinaryFormatter();
        // Show the dialog and get result.

        // Configure open file dialog box
        Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
        dlg.FileName = "Vdrop1"; // Default file name
        dlg.DefaultExt = ".vdp"; // Default file extension
        dlg.Filter = "Vdrop documents (.vdp)|*.vdp"; // Filter files by extension
        string path = Directory.GetCurrentDirectory();//use working directory
        dlg.InitialDirectory = path;

        // Show open file dialog box
        Nullable<bool> result = dlg.ShowDialog();

        //Process open file dialog box results
         if (result == true)
        {
            // Open document
            string filename = dlg.FileName;
            FileStream loadFile = new FileStream(filename, FileMode.Open,      FileAccess.Read);
            dCSelections = serializer.Deserialize(loadFile) as DCSelections;
            loadFile.Close();

        }
    }

    private void Save_Click(object sender, RoutedEventArgs e)
    {
        IFormatter serializer = new BinaryFormatter();
        // Configure save file dialog box
        Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
        dlg.FileName = "Vdrop1"; // Default file name
        dlg.DefaultExt = ".vdp"; // Default file extension
        dlg.Filter = "Vdrop documents (.vdp)|*.vdp"; // Filter files by extension
        string path = Directory.GetCurrentDirectory();//use working directory
        dlg.InitialDirectory = path;

        // Show save file dialog box
        Nullable<bool> result = dlg.ShowDialog();

        // Process save file dialog box results
        if (result == true)
        {
            // Save document
            string filename = dlg.FileName;
            FileStream saveFile = new FileStream(filename, FileMode.Create, FileAccess.Write);
            serializer.Serialize(saveFile, dCSelections);
            saveFile.Close();

        }
    }

//我知道它会反序列化。但是我的屏幕（WPF）没有显示SystemVoltage的反序列化值。这是我编写的第一个c＃代码，我可能没有正确发布这些注释和代码。对不起，我很难过。
