I have the following code, which works when I don't have the attachment.add line. (I've blanked out the addresses & password).

Please help, I guess I'm doing something wrong with the attachment I'm just not sure what!

The inner exception is

{System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'ReferenceReadStream'. at
System.Net.Mime.MimeBasePart.EndSend(IAsyncResult asyncResult) at
System.Net.Mail.Message.EndSend(IAsyncResult asyncResult) at
System.Net.Mail.SmtpClient.SendMessageCallback(IAsyncResult result)}

    [HttpPost]

    public async Task<String> PostProfilePicture(IFormFile file, int ID)

    {

        var name = Guid.NewGuid().ToString("N").ToUpper() + ".png";

        try

        {

            var stream = file.OpenReadStream();

            await sendEmail(stream, name);

        }

        catch (Exception ex)

        {

            return ex.Message.ToString();

        }



       return ""

    }



  public async Task sendEmail(Stream stream, String filename){

        var attachment = new Attachment(stream, filename);



        var smtpClient = new SmtpClient



        {

            Host = "smtp.gmail.com", // set your SMTP server name here

            Port = 587, // Port 

            EnableSsl = true,

            Credentials = new NetworkCredential("xxxxxxx@gmail.com", "xxxxxxxx")

        };



        var message = new MailMessage("xxxxxxx@gmail.com", "xxxxxxx@gmail.com");





            message.Subject = "Hello Alec!!";

            message.Body = "How are you doing.";

            message.Attachments.Add(attachment);









            await smtpClient.SendMailAsync(message);

        }

    }

I think the stream is no read to end:

Try:

    var fileContent = stream.ReadToEnd();

    var attachment = new Attachment(fileContent, filename);



    var smtpClient = new SmtpClient

Perhaps You have to read the filcontent before calling SendEmail

I think the stream needs to be readable, add

[HttpPost]

public async Task<String> PostProfilePicture(IFormFile file, int ID)

{

    var name = Guid.NewGuid().ToString("N").ToUpper() + ".png";

    try

    {

        await sendEmail(file, name); //send the file not the open read stream

    }

    catch (Exception ex)

    {

        return ex.Message.ToString();

    }



   return "";

}







public async Task sendEmail(IFormFile file, String filename){



        using(var stream = file.OpenReadStream()){ //You open your stream here

        var attachment = new Attachment(stream, filename);



        var smtpClient = new SmtpClient



        {

            Host = "smtp.gmail.com", // set your SMTP server name here

            Port = 587, // Port 

            EnableSsl = true,

            Credentials = new NetworkCredential("xxxxxxx@gmail.com", "xxxxxxxx")

    };



    var message = new MailMessage("xxxxxxx@gmail.com", "xxxxxxx@gmail.com");





        message.Subject = "Hello Alec!!";

        message.Body = "How are you doing.";

        message.Attachments.Add(attachment);



        await smtpClient.SendMailAsync(message);

    }

}

    }
