C# example code for EML message report generation


    // create a template from MailMessage
    MailMessage template = new MailMessage();
    // add template field to subject
    template.Subject = "Hello, #FirstName#";
    template.From = new MailAddress("This email address is being protected from spambots. You need JavaScript enabled to view it.", "This email address is being protected from spambots. You need JavaScript enabled to view it.");
    // add template field to receipt
    template.To.Add(new MailAddress("#Receipt#", true));
    // add template field to html body
    template.HtmlBody = "Dear #FirstName# #LastName# Sent Date: #Date#";
    // create a new TemplateEngine with the template message.
    var engine = new Email.Tools.Merging.TemplateEngine(template);
    
    // fill a DataTable
    var dt = new System.Data.DataTable();
    dt.Columns.Add("Receipt", typeof(string));
    dt.Columns.Add("First Name", typeof(string));
    dt.Columns.Add("Last Name", typeof(string));
    dt.Columns.Add("Date", typeof(DateTime));
    System.Data.DataRow dr;
    
    dr = dt.NewRow();
    dr["Receipt"] = "This email address is being protected from spambots. You need JavaScript enabled to view it.";
    dr["First Name"] = "Nancy";
    dr["Last Name:"] = "Davolio";
    dr["Date"] = System.DateTime.Now;
    dt.Rows.Add(dr);
    
    dr = dt.NewRow();
    dr["Receipt"] = "This email address is being protected from spambots. You need JavaScript enabled to view it.";
    dr["First Name"] = "Andrew";

    dr["Date"] = System.DateTime.Now;
    dt.Rows.Add(dr);
    
    // map columns
    var mappings = new System.Data.Common.DataColumnMappingCollection();
    mappings.Add(new System.Data.Common.DataColumnMapping("Receipt", "Receipt"));
    mappings.Add(new System.Data.Common.DataColumnMapping("First Name", "FirstName"));
    mappings.Add(new System.Data.Common.DataColumnMapping("Last Name", "LastName"));
    mappings.Add(new System.Data.Common.DataColumnMapping("Date", "Date"));
    Aspose.Email.MailMessageCollection messages;
    
    //  create messages from engine
    messages = engine.Instantiate(dt, mappings);
    for (int i = 0; i < messages.Count; i++)
    {
        // save messages in EML format
