ProtoInclude for fields ?
- by Big
I have a simple object
[ProtoContract]
public class DataChangedEventArgs<T> : EventArgs
{
private readonly object key;
private readonly T data;
private readonly DataChangeType changeType;
///<summary>
/// Key to identify the data item
///</summary>
public object Key
{
get { return key; }
}
[ProtoMember(2, IsRequired = true)]
public T Data
{
get { return data; }
}
[ProtoMember(3, IsRequired = true)]
public DataChangeType ChangeType
{
get { return changeType; }
}
and I have a problem with the key. Its type is object, but it can be either int, long or string.
I would intuitively use a ProtoInclude attribute to say "expect these types" but unfortunately they are class only attribute.
Does anybody has any idea how I could work around this ?
For background, the public object Key is here for historical reasons (and all over the place) so I would very much like to avoid the mother of all refactorings ;-)
Any chance I could get this to Serialize, even force it to Serialize as a string ?
