using Leadtools.Dicom.Common.Anonymization; 
 
 
public void MacroProcessorSample() 
{ 
   MacroProcessor<object> processor = new MacroProcessor<object>(); 
 
   // 
   // add two macros to the macro processor 
   // 
   processor.Macros.Add("current_date", new MacroSubstitutionDelegate<object>(CurrentDateMacro)); 
   processor.Macros.Add("current_time", new MacroSubstitutionDelegate<object>(CurrentTimeMacro)); 
 
   // 
   // Process a macro string 
   // 
   Console.WriteLine(processor.Process(processor, "${current_date} ==> ${current_time}")); 
} 
 
private string CurrentDateMacro(object userData, string name, params object[] parameters) 
{ 
   return DateTime.Now.ToShortDateString(); 
} 
 
private string CurrentTimeMacro(object userData, string name, params object[] parameters) 
{ 
   return DateTime.Now.ToShortTimeString();
