使用 Telegram - API 接收照片 [英] Receive photos with Telegram - API

问题描述

有没有办法在 C# 中使用 NuGet Telegram.Bot 接收和保存照片?

Is there a way to receive and save photos with the NuGet Telegram.Bot in C#?

另外，如何获取消息类型，我试过了

Also, how can I get the message type, i tried

if (message.Type == MessageType.PhotoMessage)

但是没有用.

推荐答案

这只是对类型的检查.完成此检查后，您可以从照片对象中获得不同的照片尺寸.

This is just the check for the type. After this check you can get different photosizes from the Photo-Object.

_telegramClient = new TelegramBotClient(ConfigurationManager.AppSettings["TelegramApiKey"]);
_telegramClient.OnMessage += BotOnMessageReceived;
_telegramClient.StartReceiving();

var test = await _telegramClient.GetFileAsync(message.Photo[message.Photo.Count() - 1].FileId);

var image = Bitmap.FromStream(test.FileStream);

image.Save(@"C:\\Users\xxx\Desktop\test.png");

// message.Photo.Count()-1 => the biggest resolution
