CMsgClientMMSLobbyChatMsg help

Hello dear users,
I need help with CMsgClientMMSLobbyChatMsg.

I need to update some text-packets, i can't understand how to do it.


var resp = new ClientMsgProtobuf<CMsgClientMMSLobbyChatMsg>(packe tMsg);
string lobby_message = (BitConverter.ToString(resp.Body.lobby_message)).T oUpper();
lobby_message = lobby_message.Replace("-", "");
if (lobby_message == "000034FB0053797353657373696F6E3A3A4F6E55706461746 50000557064617465000073797374656D00016C6F636B00000 B0067616D6500016D6D717565756500736561726368696E670 00261707200000000030B0B0B0B")
{
searchstatus = "searching game..";
}
string hex = RemoveControlCharacters(System.Text.Encoding.UTF8. GetString(resp.Body.lobby_message)) + "END";
string name = getBetween(hex, "name", "chat") + ":";
string chat = getBetween(hex, "chat", "END");
if (chat != null)
{
chat1 = name + chat;
}
resp = null;

P.S. - Im new in C# and coding. Thank you.
