在c#中序列化2D对象数组时遇到问题

我有一个2D对象数组。层次结构如下所示:

PixelData : ISerializable
-Rectangle
-SerialColor
SerialColor : ISerializable
-R
-G
-B

当我序列化它们的2d数组时，我没有得到错误消息。但是，我在文本编辑器中打开它序列化的文件，注意到大约在第10行之后，它开始破坏数据。数组的大小是50 x 50。我试过用不同的方法序列化对象。同样，在序列化数据时不会出现错误消息。当我试图反序列化数据时，我得到了可怕的异常。我该怎么办?

例外是System.Reflection.TargetInvocationException: exception has been thrown by the target of an invocation

[Serializable()]
public class PixelData : ISerializable
{
    #region Constructors
    public PixelData()
        : this(new Rectangle(0, 0, 0, 0), Color.White)
    {
    }
    public PixelData(Rectangle r, Color c)
    {
        this.BoundingRect = r;
        this.CellColor = c;
    }
    public PixelData(SerializationInfo info, StreamingContext ctxt)
    {
        this.BoundingRect = (Rectangle)info.GetValue("BoundingRect", typeof(Rectangle));
        SerialColor c = (SerialColor)info.GetValue("CellColor", typeof(SerialColor));
        this.CellColor = c.GetColor();
    }
    #endregion
    public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
    {
        info.AddValue("BoundingRect", BoundingRect);
        info.AddValue("CellColor", new SerialColor(CellColor));
    }
    #endregion
    #region Properties
    public Rectangle BoundingRect
    {
        get;
        set;
    }
    public Color CellColor
    {
        get;
        set;
    }
    #endregion
}

和SerialColor类

[Serializable()]
public class SerialColor : ISerializable
{
    public SerialColor()
        : this(0, 0, 0)
    {
    }
    public SerialColor(int r, int g, int b)
    {
        R = r;
        G = g;
        B = b;
    }
    public SerialColor(Color c)
    {
        R = c.R;
        G = c.G;
        B = c.B;
    }
    public SerialColor(SerializationInfo info, StreamingContext ctxt)
    {
        R = (int)info.GetValue("R", typeof(int));
        G = (int)info.GetValue("G", typeof(int));
        B = (int)info.GetValue("B", typeof(int));
    }
    #endregion
    #region Methods
    public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
    {
        info.AddValue("R", R);
        info.AddValue("G", G);
        info.AddValue("B", B);
    }
    public Color GetColor()
    {
        Color c =  Color.FromArgb(R, G, B);
        try
        {
            //this will throw an exception if the name of the color is not hexadecimal
            Int32.Parse(c.Name, System.Globalization.NumberStyles.HexNumber);
            //attempt to create a non-hex name for the color
            return ColorTranslator.FromHtml("#" + c.Name);
        }
        catch (Exception e)
        {
            //returns the name if it is not hexadecimal
            return c;
        }
    }
    public override string ToString()
    {
        Color c = this.GetColor();
        return c.Name + "[ " + c.R.ToString() + " , " + c.G.ToString() + " , " + c.B.ToString() + " ]";
    }
    public override bool Equals(object obj)
    {
        if (!(obj is SerialColor))
            return false;
        SerialColor other = (SerialColor)obj;
        return ((this.R == other.R) && (this.G == other.G) && (this.B == other.B));
    }
    public override int GetHashCode()
    {
        return this.GetColor().GetHashCode();
    }
    #endregion
    #region Properties
    public int R
    {
        get;
        set;
    }
    public int G
    {
        get;
        set;
    }
    public int B
    {
        get;
        set;
    }
    #endregion
}

编辑:好的，我还创建了一个SerialRectangle类，因为我浏览了文档，发现Rectangle是一个结构体。这个类与SerialColor类非常相似。
