How to Serialize Point, Pen, and Brush?

Question

See more:

I am using custom linked list, where I can able to serialize instance of Pen, Point etc.
But if I take Point and Pen object in simple class (without linked list), I can not serialize instance of Point and Pen.

Linked List class is like this

MIDL

[Serializable]
public class LinkedList
{
    // various methods to maintain First, Last, Next, Previous Node information like
    public void Add(Node node)
      {
        ......
    }
    public void Remove(Node node)
      {
        ......
    }

    //Node classs
    [Serializable]
      public class Node
      {
        public Point PointData
            {
                get;
                set;
            }
        public Node Next
            {
                get;
            set;
            }
    }
}

I can serialize LinkedList instance using below code

BinaryFormatter formatter = new BinaryFormatter()
formatter.Serialize(file, objLinkedList);

It is working fine, but if I use class like

C#

[Serializable]
 public class OverlayPoint
 {
    public Point ObjPoint
       {
            get;
            set;
       }
       public Pen ObjPen
       {
            get;
            set;
       }
}

Then I cannot serialize showing error like

Type 'System.Drawing.Pen' in Assembly 'System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.

Just because of internal class in linked list it is not firing error.
I could not able understand why this happened

Thanks for your time

Hi,

I use the following Extension to Serialize object to string.

C#

public static string SerializeObjectToString<T>(this T objectToSerialize)
        {
            StringWriter outStream = new StringWriter();
            string value;
            try
            {
                XmlSerializer s = new XmlSerializer(objectToSerialize.GetType());
                s.Serialize(outStream, objectToSerialize);
                value = outStream.ToString();
            }
            finally
            {
                outStream.Close();
            }
            return value;
        }

To then serialize your object you would use like follow.

Node myNode = new Node {PointData = new Point(10, 50), Next = new Node {PointData = new Point(30, 50)}};

Console.WriteLine(myNode.SerializeObjectToString());

View result below.

<br />
"<?xml version=\"1.0\" encoding=\"utf-16\"?><br />
<Node xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">  <PointData><br />
    <X>10</X><br />
    <Y>50</Y><br />
    </PointData><br />
    <Next><br />
        <PointData><br />
            <X>30</X><br />
            <Y>50</Y><br />
        </PointData><br />
    </Next><br />
</Node><br />

Hope this helps.
