Serializing System.Drawing.Color in .NET

Question

I\'ve used the default .NET serialization for a class with a System.Drawing.Color member. The code is now in use by people, and I need to add an extra member to the class, but

Answer 1

I have used something like this in the past.

 <Xml.Serialization.XmlIgnore()> Public BackColour As Drawing.Color

        Public Property xmlBackColour() As Integer
            Get
                Return BackColour.ToArgb
            End Get
            Set(ByVal value As Integer)
                BackColour = Drawing.Color.FromArgb(value)
            End Set
        End Property

Answer 2

Using ISerializable is not the recommended way to deal with versioning. The [OptionalField] is, the ins and outs are well described in this MSDN library article.

Answering your question: SerializationInfo.GetValue("fieldName", typeof(Color)) ought to give you the color. You'll need to cast the return value.
