Aspose.Network 3.0 is the next major official release version of our comprehensive network programming components.
Here is what’s new in Aspose.Network 3.0:
- Unique Object Model for E-Mail creating and parsing functions. The MailMessage class provides the unique and simple entry for creating and parsing E-Mail messages.
- Example
//Load outlook message format file (*.msg) to MailMessage instance
MailMessage message = MailMessage.Load(@”../message.msg”, MessageFormat.Msg);
SmtpClient client = new SmtpClient(“localhost”,”test001″, “test”);
//Send the message via Smtp
client.SendAsync(message); - Enhanced IMAP component for adding more functions and tuning performance.
- Improved POP3 component for adding more functions and tuning performance.
- Supports loading and parsing Microsoft Outlook E-Mail Message Format (*.Msg). Aspose.Network 3.0 is the FIRST .NET component provides the function to parse the Outlook message file.
- Supports loading and parsing Microsoft Html Format file (*.mht). Aspose.Network 3.0 can load a mht file and send it out through SMTP server.
- Supports loading and parsing RFC 822 compliant Email Message Format file (*.eml), and send it out through SMTP server.
- High compatible with .NET 2.0 E-Mail APIs, and Work fine under .NET 1.1 and .NET 2.0 frameworks. Therefore, .NET developers can easily migrate their E-Mail applications to Aspose.Network.
- Example code
// Command line argument must the SMTP host.
SmtpClient client = new SmtpClient(“localhost”, “test001”, “test”);
// Specify the e-mail sender.
// Create a mailing address that includes a UTF8 character
// in the display name.
MailAddress from = new MailAddress(“test001@aspose.com”,
“Jane ” + (char)0xD8 + ” Clayton”);
// Set destinations for the e-mail message.
MailAddress to = new MailAddress(“test002@aspose.com”);
// Specify the message content.
MailMessage message = new MailMessage(from, to);
message.TextBody = “This is a test e-mail message sent by an application. “;
// Include some non-ASCII characters in body and subject.
string someArrows = new string(new char[] { ‘\u2190’, ‘\u2191’, ‘\u2192’, ‘\u2193’ });
message.TextBody += Environment.NewLine + someArrows;
message.BodyEncoding = System.Text.Encoding.UTF8;
message.Subject = “test message 1” + someArrows;
message.SubjectEncoding = System.Text.Encoding.UTF8;
// Set the method that is called back when the send operation ends.
client.SendCompleted += new
SendCompletedEventHandler(SendCompletedCallback);
// The userState can be any object that allows your callback
// method to identify this send operation.
// For this example, the userToken is a string constant.
string userState = “test message1”;
client.SendAsync(message, userState);
- Sophisticated Template-based MailMerge features due to new template rendering engine.
- Aspose.Network 3.0 supports generate E-Mail messages from DataTable, DataRow and DataReader
- The template could be a run-time MailMessage instance and Eml format file.
- Aspose.Network 3.0 supports template merge against a runtime MailMessage, which can be use to add extra format info the E-Mail message like pre-defined signature in the Microsoft Outlook.
- Aspose.Nework is the FIRST .NET component that supports to use User defined function in the E-Mail template. With using function field in the template, we can easily do lots of amazing things like provide unique signature and ect.
Example code
//template routine to provide signature
static object GetSignature(object[] args)
{
return “John Smith<br>Product Lead<br>Aspose Ltd.<br>” + DateTime.Now.ToShortDateString();
}
static void Main(string[] args)
{
//create a new MailMessage instance as a template
MailMessage template = new MailMessage();
//add template field to subject
template.Subject = “Hello, #FirstName#”;
template.From = “sale@aspose.com”;
//add template field to receipt
template.To.Add(new MailAddress(“#Receipt#”, false));
//add template field to html body
//use GetSignment as the template routine, which will provide the same signature.
template.HtmlBody = “Dear #FirstName# #LastName#,<br><br>”;
template.HtmlBody += “Thank you for your interest in <STRONG>Aspose.Network</STRONG>.”;
//use user-defined routine
template.HtmlBody += “<br><br>Have fun with it.<br><br>#GetSignature()#”;
//create a new TemplateEngine with the template message.
TemplateEngine engine = new TemplateEngine(template);
//register the GetSignment as a templat routine, for we use it in the template.
engine.RegisterRoutine(“GetSignature”, new TemplateRoutine(GetSignature));
//fill a DataTable as data source
DataTable dt = new DataTable();
dt.Columns.Add(“Receipt”, typeof(string));
dt.Columns.Add(“FirstName”, typeof(string));
dt.Columns.Add(“LastName”, typeof(string));
DataRow dr;
dr = dt.NewRow();
dr[“Receipt”] = “Nancy.Davolio<Nancy@somedomain.com>”;
dr[“FirstName”] = “Nancy”;
dr[“LastName”] = “Davolio”;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[“Receipt”] = “Andrew.Fuller<Andrew@somedomain.com>”;
dr[“FirstName”] = “Andrew”;
dr[“LastName”] = “Fuller”;
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[“Receipt”] = “Janet.Leverling<Janet@somedomain.com>”;
dr[“FirstName”] = “Janet”;
dr[“LastName”] = “Leverling”;
dt.Rows.Add(dr);
MailMessageCollection messages;
try
{
//create the messages from the template and datasource.
messages= engine.Instantiate(dt);
SmtpClient client = new SmtpClient(“smtp.somedomain.com”, 25, “someone”,”password”);
//bulk send the message
client.BulkSendAsync(messages);
}
catch (MailException ex)
{
System.Diagnostics.Debug.WriteLine(ex.ToString());
}
catch (SmtpException ex)
{
System.Diagnostics.Debug.WriteLine(ex.ToString());
}
}
