使用System.Net.Mail.SmtpClient發送的電子郵件的字體大小

Question

我有一個經過廣泛測試的ASP.Net Web應用程序。它的一部分使用System.Net.Mail.SmtpClient自動發送一封電子郵件。在測試期間，從各種Windows 7機器發送電子郵件並將其格式化爲合理的字體大小。我不會在代碼中設置字體大小，順便說一句。現在應用程序已投入使用，第一封電子郵件以非常小的字體發送，用戶希望增加字體大小。我可以硬編碼字體大小，但我更願意理解這裏發生了什麼。什麼決定字體大小？它是否在SmtpClient中，或SMTP服務器上的某些設置，或什麼？以下是發送電子郵件的代碼。 TemplateEditor是頁面上的AjaxControlToolkit.HTMLEditor控件。 AttyParaMessageBody是包含電子郵件正文的變量。我們的用戶在Windows 7上使用Outlook 2010

string AttyParaMessageBody = TemplateEditor.Content; 
LHEmail.SendEmail(LHClassLibrary.LHConfigurationManager.AppSettings["ApprovedNewVersionLHEmailSubject"].ToString(), AttyParaMessageBody, AttyParaAddressees, CurrentLitHoldDetails.ResponsibleAttorney.Email, LHClassLibrary.LHConfigurationManager.AppSettings["EmailCCList"].ToString() + ";" + tbEmails.Text); 

public static void SendEmail(string subject, string body, string to, string from, string cc) 
    { 
     SendEmail(subject, body, to, from, cc, "", "", MailPriority.High); 
    } 

public static void SendEmail(string subject, string body, string to, string from, string cc, string bcc, string fileName, MailPriority Priority) 
    { 

     MailMessage msgMail = new MailMessage(); 
     SmtpClient emailClient = new SmtpClient(); 
     try 
     { 
      msgMail = BuildMessage(subject, body, to, cc, bcc, from, fileName, Priority); 
      emailClient.Send(msgMail); 
     } 
     catch (Exception ex) 
     { 
      string exception = ex.ToString(); 
     } 
     finally 
     { 
      msgMail.Dispose(); 
     } 
    } 

private static MailMessage BuildMessage(string subject, string body, string to, string cc, string bcc, string from, string fileName, MailPriority Priority) 
    { 
     MailMessage msgMail = new MailMessage(); 

     if (!to.Equals(string.Empty)) 
     { 
      //format emails for .NET 4.0 version 
      string[] toAddressList = to.Split(';'); 

      //Loads the To address field 
      foreach (string toaddress in toAddressList) 
      { 
       if (toaddress.Length > 0) 
       { 
        msgMail.To.Add(toaddress); 
       } 
      } 

      //optional args 
      //format emails for .NET 4.0 version 
      if (!cc.Equals(string.Empty)) 
      { 
       string[] ccAddressList = cc.Split(';'); 

       //Loads the Cc address field 
       foreach (string ccaddress in ccAddressList) 
       { 
        if (ccaddress.Length > 0) 
        { 
         msgMail.CC.Add(ccaddress); 
        } 
       } 
      } 
      if (!bcc.Equals(string.Empty)) 
      { 
       string[] bccAddressList = bcc.Split(';'); 

       //Loads the Bcc address field 
       foreach (string bccaddress in bccAddressList) 
       { 
        if (bccaddress.Length > 0) 
        { 
         msgMail.Bcc.Add(bccaddress); 
        } 
       } 
      } 
      if (!fileName.Equals(string.Empty)) 
       msgMail.Attachments.Add(new Attachment(fileName)); 

      msgMail.Priority = Priority; 
      msgMail.From = ((from == null) || (from.Equals(string.Empty))) ? new MailAddress("LitHold@kramerlevin.com", "Litigation Hold") : new MailAddress(from, "Litigation Hold"); 
      msgMail.Subject = subject; 
      msgMail.Body = body; 
      msgMail.IsBodyHtml = true; 

     } 
     else { throw new SmtpFailedRecipientException("Failed to provide destination address"); } 
     return msgMail; 
    } 

Answer 1

從我的經驗，當我需要將通過SMTP發送我的電子郵件內容進行格式化，我將使用HTML標記時，我的內容設定值變量。例如：

String content = "<h2>Thank you for your e-mail</h2><font size=4>We appreciate your feedback.<br/> We will process your request soon</font><br/>Regards."; 

如果您的內容將在後面的代碼中設置，那麼您可以使用上述方法。

希望它有幫助。
