範例

以下程式碼範例示範如何將位址加入 Bcc 位址集合。

public static void CreateBccTestMessage(string server)
{
    MailAddress from = new MailAddress("ben@contoso.com", "Ben Miller");
    MailAddress to = new MailAddress("jane@contoso.com", "Jane Clayton");
    MailMessage message = new MailMessage(from, to);
    message.Subject = "Using the SmtpClient class.";
    message.Body = @"Using this feature, you can send an email message from an application very easily.";
    MailAddress bcc = new MailAddress("manager1@contoso.com");
    message.Bcc.Add(bcc);
    SmtpClient client = new SmtpClient(server);
    client.Credentials = CredentialCache.DefaultNetworkCredentials;
    Console.WriteLine("Sending an email message to {0} and {1}.",
        to.DisplayName, message.Bcc.ToString());

    try
    {
        client.Send(message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in CreateBccTestMessage(): {0}",
            ex.ToString());
    }
}

Public Shared Sub CreateBccTestMessage(ByVal server As String)
    Dim from As MailAddress = New MailAddress("ben@contoso.com", "Ben Miller")
    Dim [to] As MailAddress = New MailAddress("jane@contoso.com", "Jane Clayton")
    Dim message As MailMessage = New MailMessage(from, [to])
    message.Subject = "Using the SmtpClient class."
    message.Body = "Using this feature, you can send an email message from an application very easily."
    Dim bcc As MailAddress = New MailAddress("manager1@contoso.com")
    message.Bcc.Add(bcc)
    Dim client As SmtpClient = New SmtpClient(server)
    client.Credentials = CredentialCache.DefaultNetworkCredentials
    Console.WriteLine("Sending an email message to {0} and {1}.", [to].DisplayName, message.Bcc.ToString())

    Try
        client.Send(message)
    Catch ex As Exception
        Console.WriteLine("Exception caught in CreateBccTestMessage(): {0}", ex.ToString())
    End Try
End Sub

備註

要將密件副本收件人加入電子郵件，請為收件人的地址建立一個 MailAddress ，然後將該物件加入該屬性回 Bcc 傳的集合中。

收件人查看電子郵件時，通常不會顯示地址 Bcc 。
