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}"));
}
