c#中对象序列化异常的ArrayList

本文关键字:ArrayList 异常 序列化 对象 | 更新日期: 2023-09-27 18:21:40

我有一个ArrayList,它由我创建的许多对象组成。我正在努力保留它。据我所知,最好的解决方案是使用二进制格式化程序。但是我的代码出了问题。无论是写作还是阅读,它都不起作用。这是我的密码;

namespace WindowsFormsApplication1
{
   public partial class Form1 : Form
   {
      private ArrayList allList = new ArrayList();    
      private FileStream fileStream;
      private MemoryStream memoryStream;
      public Form1()
      {
          InitializeComponent();
          fileStream = new FileStream("pcdata.dat",FileMode.OpenOrCreate,FileAccess.ReadWrite);
          memoryStream = new MemoryStream();
      }
      public void acceptDevice(Device receivedDevice)
      {
          //Somehow I call this method
          allList.Add(receivedDevice);
          saveDeviceDataToFileStream();
      }
      private void saveDeviceDataToFileStream()
      {
          SerializeToStream(allList).WriteTo(fileStream);
      }
      private void loadDeviceDataFromFileStream()
      {
          fileStream.CopyTo(memoryStream);
          allList = (ArrayList)DeserializeFromStream(memoryStream);
      }
      public static MemoryStream SerializeToStream(object o)
      {
          MemoryStream stream = new MemoryStream();
          IFormatter formatter = new BinaryFormatter();
          formatter.Serialize(stream, o);
          return stream;
      }
      public static object DeserializeFromStream(MemoryStream stream)
      {
          IFormatter formatter = new BinaryFormatter();
          stream.Seek(0, SeekOrigin.Begin);
          if (null == stream)
          {
             return null;
          }
          object o = formatter.Deserialize(stream);
          return o;
    }
  }
}

这是我的设备类别:

namespace WindowsFormsApplication1
{
    [Serializable]
    public class Device
    {
        public MyPanel panel;           //panel class that I created
        public String id;
        public int deviceNumber;
        public Device(String id, int deviceNumber)
        {
            panel = new MyPanel();
            this.id = id;
            this.deviceNumber = deviceNumber;
        }
    }
}

这是myPanel类:

namespace WindowsFormsApplication1
{
    public class MyPanel : TableLayoutPanel
    {
        public Panel panel1 = new Panel();
        public Panel panel2 = new Panel();
        public Panel panel3 = new Panel();
        public Panel panel4 = new Panel();
        public PictureBox pictureBox1 = new PictureBox();
        public Label nameLabel = new Label();
        public MyPanel()
        {
            //...
        }
    }
}

就是这样。当我尝试tun它时,我得到了一个例外:

SerializationException未处理

类型为的未处理异常中发生"System.Runtime.Serialization.Serialization异常"mscorlib.dll

附加信息:"WindowsFormsApplication1,版本=1.0.0.0,Culture=neutral,PublicKeyToken=null'Derlemesindeki"WindowsFormsApplication1.MyPanel"…

我不认为您能够仅仅序列化这样的控件。我建议围绕要保存的数据创建类,并使控件只负责显示。

[Serializable]
public class MyPanelInfo 
{
    public PanelInfo panel1;
    public PanelInfo panel2;
    public PanelInfo panel3;
    public PanelInfo panel4;
    public Image image;
    public string nameLabel;
    public MyPanelInfo()
    {
    }
}
[Serializable]
public class PanelInfo
{
    public string id;
    public string name;
}
