Send Email with Attachment in C#, VB.NET

This article illustrates how to create an email message with attachment and send it using Spire.Email component in C# and VB.NET.

Detail steps:

Step 1: Declare and assign three MailAddress objects.

MailAddress addressFrom = "Alice.yang@e-iceblue.com";
MailAddress addressTo = "leondavisld@outlook.com";
MailAddress adressCC = "Shawn_Smithhh@outlook.com";

Step 2: Create an email message.

MailMessage message = new MailMessage(addressFrom, addressTo);

Step 3: Set subject, text body and creation time for the message.

message.Subject = "Spire.Email Component";
message.BodyText = "Hi!\r\n"+
                "Spire.Email for .NET is a professional .NET Email library specially designed for developers to create, read and manipulate emails on any .NET (C#, VB.NET, ASP.NET) platform.";
message.Date = DateTime.Now;

Step 4: Add an attachment and the second receiver to cc.

message.Attachments.Add(new Attachment("Hydrangeas.jpg"));
message.Cc.Add(adressCC.Address);

Step 5: Create a SmtpClient instance and send the email message.

SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.outlook.com";
smtp.ConnectionProtocols = ConnectionProtocols.Ssl;
smtp.Username = addressFrom.Address;
smtp.Password = "password";
smtp.Port = 587;
smtp.SendOne(message);
