Cannot Serialize SolidColorBrush

问题

Error message that I cannot serialize a class because cannot serialize SolidColorBrush

The class has a public property of Brush

Is there a fix?

It is more complex.
I tried using a backing property that can be serialized
Problem is that I also need to Freeze the HighLight so I can be created on a BackgroundWorker
If I use a serializable backing property for HighLight then Highlight.Freeze fails

[Serializable()]
public class WordIdLenHightlight : Object
{
    private string highlightHex;
    public Int32 ID { get; private set; }
    public Byte Len { get; private set; }
    //[NonSerialized]
    public Brush Highlight { get;  private set; }
    //{ if (string.IsNullOrEmpty(highlightHex)) return null; else return new SolidColorBrush((Color)ColorConverter.ConvertFromString(highlightHex)); }
    public string HighlightHex { get { return highlightHex; } }
    public override bool Equals(Object obj)
    {
        // Check for null values and compare run-time types.
        if (obj == null) return false;
        if (!(obj is WordIdLenHightlight)) return false;
        WordIdLenHightlight comp = (WordIdLenHightlight)obj;
        return (comp.ID == this.ID);
    }
    public override int GetHashCode()
    {
        return ID;
    }
    public WordIdLenHightlight(WordIdLenHightlight w) 
    { 
        ID = w.ID; Len = w.Len; 
        Highlight = w.Highlight;
        highlightHex = w.Highlight.ToString();
        Highlight.Freeze(); 
    }
    public WordIdLenHightlight(Int32 id, byte len, Brush highlight) 
    { 
        ID = id; Len = len; 
        Highlight = highlight; 
        //highlightHex = Highlight.ToString();
        Highlight.Freeze(); 
    }
    public WordIdLenHightlight(Int32 id, byte len, string HighlightHex) 
    {
        highlightHex = HighlightHex;
        ID = id; 
        Len = len;
        Highlight = new SolidColorBrush((Color)ColorConverter.ConvertFromString(highlightHex));
        Highlight.Freeze();
    }
}

You don't say how you're serializing the class, but you can probably decorate the Brush property or its backing field by an attribute such as NonSerialized or XmlIgnore.

You might want to serialize some other information than enables you to reconstruct the Brush on deserialization, for example, its color.
