使用C＃在电报bot上上传视频？

Question

I want to upload a video on a telegram bot using c#. i have tried the one API for sending videos but i couldn't upload anything using this method. is there any limits for video uploading in bots ? please any one tell me where is my mistake.and duration is necessary to pass in the API but how can i get the video duration ? i have first downloaded the video from url using web client and then i convert it in to stream and send on bot.

here is my code =>

byte[] videoDate;
using (var wc = new WebClient())
videoDate = wc.DownloadData(videoUrl);

var response = await
_api.SendVideo(update.Message.Chat.Id,new FileToSend(videoUrl, new MemoryStream(videoDate)), 15, myBotAdMsg);

here i have pass 15 duration fi right now but here my video duration is 00:10 second so how can also fix it.

您可以尝试这样=>

Bot.SendVideoAsync(update.Message.Chat.Id, video: VideoUrl, caption: myBotAdMsg);
