计算用户进入不和谐bot语音通道的时间

Question

这似乎有效，但是当我退出语音通道时，时间仍在数据库中计算。现在我将编辑问题并添加我的代码 _client.UserVoiceStateUpdated + = UserConnection;

     public static async Task UserConnection(SocketUser arg, SocketVoiceState stat1, SocketVoiceState stat2)
            {
                var user = arg as SocketGuildUser;
    
                var profile = UsrDb.GetUserHours(user.Id, user.Guild.Id);
    
               

            if (profile == null)
            {
                profile = new Usr
                {
                    UserId = user.Id,
                    GuildId = user.Guild.Id
                };
            }

            profile.startTime = DateTime.UtcNow;


            await UsrDb.SetUsr(profile); //recording time in the database

        }

[Command("check user time")]
        public async Task UserTimeCheck()
        {
            var profile = UsrDb.GetUserHours(Context.User.Id, Context.Guild.Id);

            var eb = new EmbedBuilder();

            if (profile == null)
            {
                await ReplyAsync($"{Context.User.Username} your time 0 hours 0 minutes 0 second");
            }

            profile.endTime = DateTime.UtcNow;

            TimeSpan total = profile.endTime - profile.startTime;

            eb.WithAuthor($"{Context.User.Username} - Your voice time");
            eb.WithDescription($"{total.Hours} hrs | {total.Minutes} min | {total.Seconds} sec.");
            await ReplyAsync(embed: eb.Build());
        }
