Represents an e-mail message that can be sent using the SmtpClient class.

Instances of the MailMessage class are used to construct e-mail messages that are transmitted to an SMTP server for delivery using the SmtpClient class.
To specify the sender, recipient, and contents of an e-mail message, use the associated properties of the MailMessage class.

Use the AlternateViews property to specify copies of an e-mail message in different formats. For example, if you send a message in HTML, you might also want to provide a plain text version in case some of the recipients use e-mail readers that cannot display HTML content. For an example that demonstrates creating a message with alternate views, see AlternateViews.
After assembling your e-mail message, you can send it by using the Send or SendAsync methods.
The following code example demonstrates creating and sending an e-mail message that includes an attachment.
public static void CreateMessageWithAttachment(string server) { // Specify the file to be attached and sent. // This example assumes that a file named Data.xls exists in the // current working directory. string file = "data.xls"; // Create a message and set up the recipients. MailMessage message = new MailMessage( "jane@contoso.com", "ben@contoso.com", "Quarterly data report.", "See the attached spreadsheet."); // Create the file attachment for this e-mail message. Attachment data = new Attachment(file, MediaTypeNames.Application.Octet); // Add time stamp information for the file. ContentDisposition disposition = data.ContentDisposition; disposition.CreationDate = System.IO.File.GetCreationTime(file); disposition.ModificationDate = System.IO.File.GetLastWriteTime(file); disposition.ReadDate = System.IO.File.GetLastAccessTime(file); // Add the file attachment to this e-mail message. message.Attachments.Add(data); //Send the message. SmtpClient client = new SmtpClient(server); // Add credentials if the SMTP server requires them. client.Credentials = CredentialCache.DefaultNetworkCredentials; client.Send(message); // Display the values in the ContentDisposition for the attachment. ContentDisposition cd = data.ContentDisposition; Console.WriteLine("Content disposition"); Console.WriteLine(cd.ToString()); Console.WriteLine("File {0}", cd.FileName); Console.WriteLine("Size {0}", cd.Size); Console.WriteLine("Creation {0}", cd.CreationDate); Console.WriteLine("Modification {0}", cd.ModificationDate); Console.WriteLine("Read {0}", cd.ReadDate); Console.WriteLine("Inline {0}", cd.Inline); Console.WriteLine("Parameters: {0}", cd.Parameters.Count); foreach (DictionaryEntry d in cd.Parameters) { Console.WriteLine("{0} = {1}", d.Key, d.Value); } data.Dispose(); }

And what about authentication with the smtp server?
See the SmtpClient class. That controls credentials.
Where is the VB example? If you are tryingl to discourage the use of VB, just say so. Grow up and say what you mean.
