對於Discord.NET，檢查消息是否通過前綴命令應已由異步處理程序處理。

如果你按照文檔/源代碼的例子，你可以搜索文件中某處的HandleCommandAsync函數。

從文檔的例子

基本上，它看起來像這樣：

private async Task HandleCommandAsync(SocketMessage arg) 
    { 
     // Bail out if it's a System Message. 
     var msg = arg as SocketUserMessage; 
     if (msg == null) return; 

     // Create a number to track where the prefix ends and the command begins 
     int pos = 0; 
     // Replace the '!' with whatever character 
     // you want to prefix your commands with. 
     // Uncomment the second half if you also want 
     // commands to be invoked by mentioning the bot instead. 
     if (msg.HasCharPrefix('!', ref pos) /* || msg.HasMentionPrefix(_client.CurrentUser, ref pos) */) 
     { 
      // Create a Command Context. 
      var context = new SocketCommandContext(_client, msg); 

      // Execute the command. (result does not indicate a return value, 
      // rather an object stating if the command executed succesfully). 
      var result = await _commands.ExecuteAsync(context, pos, _services); 

      // Uncomment the following lines if you want the bot 
      // to send a message if it failed (not advised for most situations). 
      //if (!result.IsSuccess && result.Error != CommandError.UnknownCommand) 
      // await msg.Channel.SendMessageAsync(result.ErrorReason); 
     } 
    }

通知部分msg.HasCharPrefix('!', ref pos)？
基本上，它會在嘗試執行命令之前檢查消息是否包含所需的前綴。如果沒有，那麼它什麼也不做。
（請注意，msg.HasStringPrefix()也存在！）

Wen Qin，我插入了代碼，並將行縮小爲3行錯誤，但在這些錯誤中，我不知道爲什麼它不會識別_services _commands和_client – Xpresnvdy

代碼是從文檔的示例中提取的。 _client是你聲明的'DiscordSocketClient'，_commands是你聲明的'CommandService'，最後_services是你的'IServiceProvider'。你可以在這裏查看文檔的教程：https://discord.foxbot.me/docs/guides/getting_started/intro.html – WQYeo
