Serialization of FastLine Series

[asupriya]

Is there a way I can serialize an array of fastline series? I tried the following, but the runtime gives the following error.

Code: Select all

System.Runtime.Serialization.SerializationException was unhandled
  Message="Type 'System.ComponentModel.Component' in Assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable."

The code I used is:

Code: Select all

[Serializable()] 
    class MySerializable: ISerializable 
    {
        public Steema.TeeChart.Styles.FastLine fastline1;
        public MySerializable()
        {
            fastline1 = null;
        }

        //Serialization function.
        public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
        {
            info.AddValue("fastline1", fastline1);
        }
        //Deserialization constructor.
        public MySerializable(SerializationInfo info, StreamingContext ctxt)
        {
            //Get the values from info and assign them to the appropriate properties
            fastline1 = (Steema.TeeChart.Styles.FastLine)info.GetValue("fastline1", typeof(Steema.TeeChart.Styles.FastLine));
        }

    }

Hi asupriya,

For serialization of custom objects please read tutorial 19. Tutorials can be found at TeeChart's program group.

Thanks in advance.

Thanks. I like to serialize simply the Fastline series array and not the whole chart (as shown in the Tutorial 19). Is there a way to do so?

I need to save multiple charts data into a single file. So, saving to .ten on a per chart basis is not a solution that is applicable for my case.

Thanks,

Hi asupriya,

In that case you can use XML data export format supplied and load back series and data from it. You'll find information and examples in tutorial 12. Tutorials are available at TeeChart's program group.
