Examples

Note Note
In real-world apps, it's easier to use Add(String) overload to add an attachment from a file.
// To use the code below, import these namespaces at the top of your code.
using System.IO;
using MailBee;
using MailBee.Mime;

// Create new data buffer as binary array.
byte[] fileData = null;

// Open a file for reading.
using (FileStream fs = new FileStream(@"C:\Temp\1.gif", FileMode.Open))
{
    // Set the size of the buffer.
    fileData = new byte[fs.Length];

    // Create new BinaryReader object.
    BinaryReader br = new BinaryReader(fs);

    // Read binary data from file to buffer.
    br.Read(fileData, 0, fileData.Length);
}

// Create a new MailMessage object.
MailMessage msg = new MailMessage();

// Add an attachment to the message.
msg.Attachments.Add(fileData, "my.gif", "<12s4a8a8778c$5664i1b1$ir671781@tlffmdqjobxj>", "image/gif", null, NewAttachmentOptions.None, MailTransferEncoding.Base64);
