[lucaswhob]

I Used RequestGetParticipants To get Participants Of Group But No Success
my code is :
TChannel t = (TChannel)item; RequestGetParticipants rgp = new RequestGetParticipants(); TInputChannel tic = new TInputChannel(); tic.AccessHash = t.AccessHash; tic.ChannelId=t.Id; rgp.Channel = tic; rgp.Limit = 5; rgp.Offset = 0; var participants = (TChannelParticipants)clientApi.CustomRequestsService.SendRequestAsync(rgp).GetAwaiter().GetResult();
but last Line Throw Exception DotNetty
