BinaryFormatter.Serialize not working

I am trying to serialize an object into a binary file. I am using BinaryFormatter.Serialize to serialize the object, but when I try to call it, I get a parser error on the stream argument, "Unexpected symbol `(' in class, struct, or interface member declaration".

This is my code:

using UnityEngine;
using System.Collections;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

public class Serializer{
    Properties prop = new Properties ();
    IFormatter f = new BinaryFormatter();
    Stream s = new FileStream("Properties/prop.bin", FileMode.Create, FileAccess.Write, FileShare.None);
    f.Serialize(s, prop);
    s.Close();
}

The error is on:

f.Serialize(s, prop); //the error is on the 's'

and I am getting the same error here:

s.Close();

How can I fix these errors?

Here is what I am serializing:

public class Properties{
    public string y = "2";
    public string x = "4";
}

Your code needs to be inside a function. 

public class Serializer{

    public void Seralize()
    {
        Properties prop = new Properties ();
        IFormatter f = new BinaryFormatter();
        Stream s = new FileStream("Properties/prop.bin", FileMode.Create, FileAccess.Write, FileShare.None);
        f.Serialize(s, prop);
        s.Close();
    }

}

However I would recommend you avoid BinaryFormatter assembly version changes can easily break your file, use XML or some other binary formatter instead.
