Convert any object to a byte[]

by

Use the BinaryFormatter:

byte[] ObjectToByteArray(object obj)
{
    if(obj == null)
        return null;
    BinaryFormatter bf = new BinaryFormatter();
    using (MemoryStream ms = new MemoryStream())
    {
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }
}

Note that obj and any properties/fields within obj (and so-on for all of their properties/fields) will all need to be tagged with the Serializable attribute to successfully be serialized with this.
