我正在尝试制作一条自动 BannedUser 消息，它说我缺少一个参数

Question

错误：“UserBanned”没有重载匹配委托“Func”

我知道我被禁止的用户消息缺少一个参数，并且我知道我必须在该参数的括号中添加一些内容，但我完全不知道我应该输入什么。我已经寻找了一两个小时，也许答案就在我脸上，但我不知道，但我仍然不知道该怎么办。我想我应该在括号中添加一个变量，但我不确定是什么。

public async Task RunBotAsync()
    {
        _client = new DiscordSocketClient(new DiscordSocketConfig
        {
            LogLevel = LogSeverity.Verbose
        });
        _commands = new CommandService();
        _services = new ServiceCollection()
            .AddSingleton(_client)
            .AddSingleton(_commands)
            .BuildServiceProvider();

        string botToken = "Token";

        //event subscriptions
        _client.Log += Log;
        _client.UserJoined += UserJoined;
        _client.UserLeft += UserLeft;
        _client.UserBanned += UserBanned; //<- Error Line

        await RegisterCommandsAsync();

        await _client.LoginAsync(TokenType.Bot, botToken);

        await _client.StartAsync();

        await Task.Delay(-1);
    }

    private async Task UserBanned(SocketGuildUser user, IGuild bloop)
    {
        var guild = user.Guild;
        var announcements = _client.GetChannel(390418472783577088) as SocketTextChannel;
        await announcements.SendMessageAsync($"{user.Mention} was banned from the server.");
    }

Answer 1

从行：

_client.UserBanned += UserBanned;

引用的函数应该如下所示。

async Task UserBanned(SocketUser user, SocketGuild bloop)
{
    var guild = user.Guild;
    var announcements = _client.GetChannel(390418472783577088) as SocketTextChannel;
    await announcements.SendMessageAsync($"{user.Mention} was banned from the server.");
}

Discord.WebSocket.BaseSocketClient.UserBanned

看起来您需要一个 SocketGuild arg 而不是 IGuild 接口。
