Aspose.Network 3.0 makes it simpler and easier to create E-Mail newsletter or subscription solutions. A new sophisticated E-Mail Template Engine is embeded, which provides lots of cool features and function and greatly reduce the the programming works.
Top Features in MailMerge:
- The First Email Component supports using Customer Defined Function in the template. For example, you can register a TemplateRoutine, and use it in the template file.
- Creates E-mail template from file
- Creates E-mail template from MailMessage instance
- Supports DataTable as data source.
- Supports DataRowCollection as data source
- Supports DataReader as data source
- Asynchronous and Synchronous programming models
- Support Event model
A new class called TemplateEngine is created, for generating the E-Mail messages from the template and data source. After the E-Mail messages is created by the TemplateEngine , Use the SmtpClient to send the messages.
Sample:
[C#]
//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>.”;
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 templet 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”);
client.BulkSendAsync(messages, null);
}
catch (MailException ex)
{
System.Diagnostics.Debug.WriteLine(ex.ToString());
}
catch (SmtpException ex)
