與使用Stringbuilder進行以下操作相比，有沒有一種更好的方法可以用C＃生成HTML電子郵件（用于通過System.Net.Mail發送）？string userName = "John Doe";StringBuilder mailBody = new StringBuilder();mailBody.AppendFormat("<h1>Heading Here</h1>");mailBody.AppendFormat("Dear {0}," userName);mailBody.AppendFormat("<br />");mailBody.AppendFormat("<p>First part of the email body goes here</p>");等等等等？
