public virtual async Task MotgaAtt(IDialogContext context, IAwaitable<IMessageActivity> argument)
{
var message = await argument;
if (message.Attachments != null && message.Attachments.Any())
{
var attachment = message.Attachments.First();
using (HttpClient httpClient = new HttpClient())
{
var responseMessage = await httpClient.GetAsync(attachment.ContentUrl);
var contentLenghtBytes = responseMessage.Content.Headers.ContentLength;
await context.PostAsync($"Attachment of {attachment.ContentType} type and size of {contentLenghtBytes} bytes received.");
}
}
context.Done<object>(new object());
}
I want to get the uploaded attachment by the bot user so i can insert it in the database. I tried to use the attachment variable i created but it seems not to be the exact file the user uploaded. Please how do i get the uploaded file?. Thanks

See official samples: https://github.com/Microsoft/BotBuilder-Samples/tree/master/CSharp/core-ReceiveAttachment
Depending on the channel you must give a specific token:
public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument)
{
var message = await argument;
if (message.Attachments != null && message.Attachments.Any())
{
var attachment = message.Attachments.First();
using (HttpClient httpClient = new HttpClient())
{
// Skype & MS Teams attachment URLs are secured by a JwtToken, so we need to pass the token from our bot.
if ((message.ChannelId.Equals("skype", StringComparison.InvariantCultureIgnoreCase) || message.ChannelId.Equals("msteams", StringComparison.InvariantCultureIgnoreCase))
&& new Uri(attachment.ContentUrl).Host.EndsWith("skype.com"))
{
var token = await new MicrosoftAppCredentials().GetTokenAsync();
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
}
var responseMessage = await httpClient.GetAsync(attachment.ContentUrl);
var contentLenghtBytes = responseMessage.Content.Headers.ContentLength;
await context.PostAsync($"Attachment of {attachment.ContentType} type and size of {contentLenghtBytes} bytes received.");
}
}
else
{
await context.PostAsync("Hi there! I'm a bot created to show you how I can receive message attachments, but no attachment was sent to me. Please, try again sending a new message including an attachment.");
}
context.Wait(this.MessageReceivedAsync);
}
