Contoh

Contoh kode berikut menampilkan nilai properti .

public static void CreateMessageWithMultipleViews(string server, string recipients)
{
    // Create a message and set up the recipients.
    MailMessage message = new MailMessage(
        "jane@contoso.com",
        recipients,
        "This email message has multiple views.",
        "This is some plain text.");

    // Construct the alternate body as HTML.
    string body = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">";
    body += "<HTML><HEAD><META http-equiv=Content-Type content=\"text/html; charset=iso-8859-1\">";
    body += "</HEAD><BODY><DIV><FONT face=Arial color=#ff0000 size=2>this is some HTML text";
    body += "</FONT></DIV></BODY></HTML>";

    ContentType mimeType = new System.Net.Mime.ContentType("text/html");
    // Add the alternate body to the message.

    AlternateView alternate = AlternateView.CreateAlternateViewFromString(body, mimeType);
    message.AlternateViews.Add(alternate);

    // Send the message.
    SmtpClient client = new SmtpClient(server);
    client.Credentials = CredentialCache.DefaultNetworkCredentials;

    try
    {
        client.Send(message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in CreateMessageWithMultipleViews(): {0}",
            ex.ToString());
    }
    // Display the values in the ContentType for the attachment.
    ContentType c = alternate.ContentType;
    Console.WriteLine("Content type");
    Console.WriteLine(c.ToString());
    Console.WriteLine("Boundary {0}", c.Boundary);
    Console.WriteLine("CharSet {0}", c.CharSet);
    Console.WriteLine("MediaType {0}", c.MediaType);
    Console.WriteLine("Name {0}", c.Name);
    Console.WriteLine("Parameters: {0}", c.Parameters.Count);
    foreach (DictionaryEntry d in c.Parameters)
    {
        Console.WriteLine("{0} = {1}", d.Key, d.Value);
    }
    Console.WriteLine();
    alternate.Dispose();
}

Keterangan

Dalam contoh header Tipe Konten berikut, nilai CharSet properti adalah "us-ascii".

content-type: application/x-myType; charset=us-ascii

Atur properti ini ke null atau String.Empty untuk menghapus informasi charset dari header.

Tata bahasa yang merinci sintaks header Jenis Konten dijelaskan dalam RFC 2045 Bagian 5.1. Diskusi mendalam tentang parameter charset terkandung dalam RFC 2046 Bagian 4.1.2. RFC ini tersedia di https://www.ietf.org.
