MailMessage::Attachments Property
.NET Framework (current version)
Gets the attachment collection used to store data attached to this e-mail message.
Assembly: System (in System.dll)
Use the collection returned by the Attachments property to add an attachment, such as a file or the contents of a Stream, to this MailMessage.
Create an Attachment that contains or references the data to be attached, and then add the Attachment to the collection returned by Attachments.
The following code example demonstrates creating and sending an e-mail message with an attachment.
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 = L"data.xls"; // Create a message and set up the recipients. MailMessage^ message = gcnew MailMessage( L"jane@contoso.com",L"ben@contoso.com",L"Quarterly data report.",L"See the attached spreadsheet." ); // Create the file attachment for this e-mail message. Attachment^ data = gcnew 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 = gcnew 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( L"Content disposition" ); Console::WriteLine( cd ); Console::WriteLine( L"File {0}", cd->FileName ); Console::WriteLine( L"Size {0}", cd->Size ); Console::WriteLine( L"Creation {0}", cd->CreationDate ); Console::WriteLine( L"Modification {0}", cd->ModificationDate ); Console::WriteLine( L"Read {0}", cd->ReadDate ); Console::WriteLine( L"Inline {0}", cd->Inline ); Console::WriteLine( L"Parameters: {0}", cd->Parameters->Count ); IEnumerator^ myEnum1 = cd->Parameters->GetEnumerator(); while ( myEnum1->MoveNext() ) { DictionaryEntry^ d = safe_cast<DictionaryEntry^>(myEnum1->Current); Console::WriteLine( L"{0} = {1}", d->Key, d->Value ); } data->~Attachment(); client->~SmtpClient(); }
