ContentDisposition::Parameters Property
.NET Framework (current version)
Gets the parameters included in the Content-Disposition header represented by this instance.
Assembly: System (in System.dll)
Property Value
Type: System.Collections.Specialized::StringDictionary^A writable StringDictionary that contains parameter name/value pairs.
Typically, the parameters are determined by the property values so you do not need to access them. If you need to add or change parameter information, modify the dictionary returned by the Parameters property.
The Content-Disposition header is described in RFC 2183, available at http://www.ietf.org.
The following code example displays the parameters that are sent to the Content-Disposition header.
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(); }
