Parameters

fileName

A String that contains the content for this attachment.

mediaType

A String that contains the MIME Content-Header information for this attachment. This value can be a null reference (Nothing in Visual Basic).

Exception typeCondition

ArgumentNullException

fileName is a null reference (Nothing in Visual Basic).

FormatException

mediaType is not in the correct format.

If mediaType is a null reference (Nothing in Visual Basic) or equal to String.Empty (""), the MediaType property for this attachment is set to Plain. If mediaType is not a null reference (Nothing in Visual Basic) and is not a zero-length string, it is used to construct the ContentType associated with this attachment.

The following code example demonstrates how to call this constructor.

public static void CreateMessageInlineAttachment(string server, string
textMessage)
{
    // Create a message and set up the recipients.
    MailMessage message = new MailMessage(
       "jane@contoso.com",
       "ben@contoso.com",
       "An inline text message for you.",
       "Message: ");

    // Attach the message string to this e-mail message.
    Attachment data = new Attachment(textMessage, MediaTypeNames.Text.Plain);
    // Send textMessage as part of the e-mail body.
    message.Attachments.Add(data);
    ContentDisposition disposition = data.ContentDisposition;
    disposition.Inline = true;
    //Send the message.
    // Include credentials if the server requires them.
    SmtpClient client = new SmtpClient(server);
    client.Credentials = CredentialCache.DefaultNetworkCredentials;
    client.Send(message);
    data.Dispose();
}
