Struct within Struct, able to change inner Struct type

[metalheadstorm]

There isn't much explaining to this, this is what I have:

 
    public struct PACKET_HEADER
    {
        public string computerIp;
        public string computerName;
        public string computerCustomName;
    };

    public struct PACKET
    {
        public PACKET_HEADER pktHdr;
        public PACKET_DATA pktData;
    };


    public struct PACKET_DATA
    {
        public Command command;
        public string data;  
    };

    public struct DATA_MESSAGE
    {
        public string message;
    };

    public struct DATA_FILE
    {
        public string fileName;
        public long fileSize;       
    };

Basically I want the data field in PACKET_DATA to be able to be either DATA_FILE or DATA_MESSAGE. I know the type needs to be changed but I don't know what to, is generics an option?

the end result should be so that I can do either:

pktData.data.fi leName
or
pktData.data.me ssage
