title: How to log to multiple targets using NLog?
body: <p>I am using NLog and I want to log to RichTextBox and File at the same time. And I want to configure the Logger programmatically, not with xml config file.</p>
  
  <p>The following code only logs to the last target (File in this case). Can anybody help?</p>
  
  <pre><code>RichTextBoxTarget t1 = new RichTextBoxTarget();
  t1.Layout = "${date} ${message}";
  t1.ControlName = "rtb_log";
  t1.FormName = "MainForm";
  NLog.Config.SimpleConfigurator.ConfigureForTargetLogging(t1, LogLevel.Debug);
  
  FileTarget t2 = new FileTarget(); 
  t2.Layout = "${date} ${level} ${message}"; 
  t2.FileName = "${basedir}/Logs/today.log"; 
  t2.KeepFileOpen = false; 
  t2.Encoding = "iso-8859-2"; 
  NLog.Config.SimpleConfigurator.ConfigureForTargetLogging(t2, LogLevel.Trace); 
  
  Logger logger = LogManager.GetLogger("MyLogger");
  </code></pre>
