Discord.Net 中的临时语音通道

Question

我在 C# 中有以下工作代码并使用 Discord.Net 但我不知道我需要做什么，删除 频道内没有用户时临时创建的频道。 我知道如何删除一个频道，但我不知道如何检查旧频道是否是临时创建的频道。 我需要检查旧频道是否是临时创建的频道，并在频道中没有用户但只有这个频道而不是其他每个频道时删除它。

这是我目前的工作代码

            _client.UserVoiceStateUpdated += HandleVoiceState;

    }
    public async Task HandleVoiceState(SocketUser user, SocketVoiceState before, SocketVoiceState after)
    {
            Console.WriteLine($"VoiceStateUpdate: {user} - {before.VoiceChannel?.Name ?? "null"} -> {after.VoiceChannel?.Name ?? "null"}");
            //needs await
        if (user is SocketGuildUser socketGuildUser)
        {
            var server = socketGuildUser.Guild;

            var categoryId = server.CategoryChannels.FirstOrDefault(category => category.Name.Equals(" Staff "))?.Id;
            

            if (socketGuildUser.VoiceState?.VoiceChannel.Id == 856855859001557012)
            {
                var voiceChannel = await server.CreateVoiceChannelAsync(socketGuildUser.Username, prop => prop.CategoryId = categoryId);
                Console.WriteLine(voiceChannel.Id);
                await socketGuildUser.ModifyAsync(x =>
                {
                    x.Channel = Optional.Create(voiceChannel as IVoiceChannel);
                });
            }
        }
    }

                            var usersVoiceChannel = (socketGuildUser as IVoiceState).VoiceChannel;
                    if (usersVoiceChannel == null)

                        {
                        if ((after.VoiceChannel != before.VoiceChannel)
                                && before.VoiceChannel.Category.Id.Equals(autocreatecategoryid) 
                                && before.VoiceChannel.Users.Count == 0 
                                && !before.VoiceChannel.Id.Equals(autocreateid))
                            {
                                await before.VoiceChannel.DeleteAsync();
                            } 
                        }else{

                        }
                        
                        
                            }
