Hey guys.
I need aid in learning how to serialise a FileSystemWatcher object.
I have a class Watch.cs:
CODE
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
[Serializable]
public class Watch
{
FileSystemWatcher monitor;
public Watch(string path)
{
monitor = new FileSystemWatcher(path);
}
}
and I am serialising it like so;
CODE
FileStream saveStream = new FileStream(System.Environment.CurrentDirectory + "\\SavedObjects.fsd", FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(saveStream, watch);
saveStream.Close();
Now i am serialising 3 other classes of mine in the exact same way and it works fine. The difference being is that my Watch.cs class holds two instances of the FileSystemWatcher class. Whenever i try and serialise this Watch.cs class i get a SerialisationException saying "Type 'System.IO.FileSystemWatcher' in Assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable."
Now I have done some brief searches on google but I cannot seem to find anyone else having a similar issue. I realise that to serialise something you must either mark it with [Serializable] attribute of make the class implement the ISerializable interface but neither is possible when its a variable within a class that's causing the fuss.
Do i really have to create my own wrapper class around this FileSystemWatcher just so i cant get it to implement the ISerlializable interface ? I cannot see that working either really as i would still have to have an instance of FileSystemWatcher within that class.
Is it possible to get a class containing a FileSystemWatcher to serialise through a BinaryFormatter or must i use the XML way of doing things because i am not so keen on that approach.
Thanks in advance for any help you may be able to give.
