Email Sender Test with FluentEmail

This is a console app that sends email with FluentEmail with a bunch of PDF files attached.

I was watching a video from Tim Corey. He does not mentioned anything about adding attachments which I needed to do. First of all, here is a link to his youtube video. Go give a like and come back! https://www.youtube.com/watch?v=qSeO9886nRM

Two ways to add attachments in FluentEmail

1. Attaching the file by file name

var email = await Email
    .From("john@email.com")
    .To("bob@email.com", "bob")
    .Subject("hows it going bob")
    .AttachFromFilename("C:\\Your Filename.pdf")
    .Body("yo bob, long time no see!")
    .SendAsync();

The obvious drawback to this method is that you can only attach a single file per email. I think... I don't see how I could add multiple files from this as there is no overload to this method.

2. Attach a FileStream...

How on earth do I do that...? BTW... not just file stream..., any stream should do... I guess. The following is how I managed to do... not near perfect since I have no idea when the file stream gets closed.

 DirectoryInfo d = new DirectoryInfo(@"C:\Export"); //Assuming Test is your Folder
 FileInfo[] Files = d.GetFiles("*.pdf"); //Getting pdf files

List<Attachment> attachments = new List<Attachment>();

// I guess you are going to make sure that the size of attachments does not 
// exceed 25 MB or something. The limit.

//may be zip them all up and attach
var attachmentSize = 0L;
foreach (var file in Files)
{
    attachmentSize += file.Length;
    attachments.Add(new Attachment()
                    {
                        ContentId = Guid.NewGuid().ToString(),
                        // if text files use somthing like : text/plain 
                        ContentType = "application/pdf", 
                        Filename = file.Name,
                        IsInline = false,
                        // I wonder when the file stream gets closed!
                        Data = new FileStream(file.FullName, FileMode.Open) 
                    });
}

//assuming that the limit is 25MB. Does't really matter unless you try to send a real one.
var attachmentSizeInMB = attachmentSize / (1024 * 1024);
Console.WriteLine($"Attachment size is {attachmentSizeInMB} MB.");
if ( attachmentSizeInMB < 25)
{
    var email = await Email
        .From("john@email.com")
        .To("bob@email.com", "bob")
        .Subject("hows it going bob")
        .Attach(attachments)
        .Body("yo bob, long time no see!")
        .SendAsync();
}
else
{
    Console.WriteLine("Attachment size exceeded 25MB");
}
