Return Value

A String that contains the current settings for this ContentType.

The value of the ToString method contains the string used to create this ContentType, if one was specified and no property values have been changed. If no string was specified, or one or more property values have changed since this ContentType was created, the value of ToString is a string in the format of a Content-Type header that is composed using the current property values. The string does not include the "Content-type:" prefix.

The syntax of the Content-Type header is described in RFC 2045 Section 5.1, available at

The following code example displays the string representation of a ContentType.

public static void CreateMessageInlineAttachment2(string server, string
    // Create a message and set up the recipients.
    MailMessage message = new MailMessage(
       "A text message for you.",
       "Message: ");

    // Attach the message string to this e-mail message.
    Attachment data = new Attachment(textMessage);
    // Send textMessage as part of the e-mail body.
    ContentType content = data.ContentType;
    content.MediaType = MediaTypeNames.Text.Plain;
    //Send the message.
    // Include credentials if the server requires them.
    SmtpClient client = new SmtpClient(server);
    client.Credentials = CredentialCache.DefaultNetworkCredentials;
