Question

我正在尝试设置自动消息。

当我设置client时，我使用：

client.Ready += OnClientReady;

从那里开始我的Scheduler课程：

private Task OnClientReady()
{
    var scheduler = new Scheduler(client);
    scheduler.Start();

    return Task.CompletedTask;
}

看起来像这样：

public class Scheduler
{
    private readonly DiscordSocketClient _client;
    private static Timer _timer;

    public void Start(object state = null)
    {
        Sender.Send(_client);

        _timer = new Timer(Start, null, (int)Duration.FromMinutes(1).TotalMilliseconds, 0);
    }

    public Scheduler(DiscordSocketClient client)
    {
        _client = client;
    }
}

当计时器滴答时，它会调出并将client传递给下面的Sender课程：

public static class Sender
{
    public static void Send(DiscordSocketClient client)
    {
        var currentLocalDateTime = SystemClock.Instance.InTzdbSystemDefaultZone().GetCurrentLocalDateTime();

        var elapsedRotations = new List<Rotations>();
        using (var db = new GOPContext())
        {
            elapsedRotations = db.Rotations
                                 .Include(r => r.RotationUsers)
                                 .Where(r => r.LastNotification == null ||
                                             Period.Between(r.LastNotification.Value.ToLocalDateTime(),
                                                            currentLocalDateTime).Hours >= 23)
                                 .ToList();
        }

        foreach (var rotation in elapsedRotations)
        {
            var zone = DateTimeZoneProviders.Tzdb.GetZoneOrNull(rotation.Timezone);
            var zonedDateTime = SystemClock.Instance.InZone(zone).GetCurrentZonedDateTime();
            if (zonedDateTime.Hour != 17)
                continue;

            //I need to send a message to the channel here.
            //I have access to the connected / ready client, 
            //and the channel Id which is "rotation.ChannelId"
        }
    }
}

我尝试过这样的频道：

var channel = client.GetChannel((ulong) rotation.ChannelId);

给了我一个SocketChannel，也是这样的：

var channel = client.Guilds
                    .SelectMany(g => g.Channels)
                    .SingleOrDefault(c => c.Id == rotation.ChannelId);

给了我一个SocketGuildChannel。这些都不能让我选择直接向频道发送消息。我试过研究如何做到这一点，但没有找到任何东西......文档似乎没有任何这方面的例子......

这似乎是一件很简单的事情，但是我的智慧结束了。有谁知道怎么做？

这是因为SocketGuildChannel和SocketChannel都可以是语音或文字频道。

相反，您需要ISocketMessageChannel，IMessageChannel或SocketTextChannel

要获得此功能，您只需投射SocketChannel即将获得

var channel = client.GetChannel((ulong) rotation.ChannelId);
var textChannel = channel as IMessageChannel;
if(textChannel == null)
    // this was not a text channel, but a voice channel
else
    textChannel.SendMessageAsync("This is a text channel");

给定已连接且准备就绪的DiscordSocketClient和Discord Channel Id，如何向该频道发送消息？
