public void BarcodeReadOptions_LoadSaveExample() 
{ 
   string xmlFileName = Path.Combine(LEAD_VARS.ImagesDir, "MyOptions.xml"); 
 
   // Create the options 
   OneDBarcodeReadOptions options1 = new OneDBarcodeReadOptions(); 
   // Show its values 
   ShowOptions("Default 1", options1); 
 
   // Change some of the values 
   options1.SearchDirection = BarcodeSearchDirection.HorizontalAndVertical; 
   options1.ReturnCheckDigit = BarcodeReturnCheckDigit.Default; 
   options1.EnableErrorCheck = true; 
   ShowOptions("New Options 1", options1); 
 
   // Save it to disk 
   options1.Save(xmlFileName); 
 
   // Create new options 
   OneDBarcodeReadOptions options2 = new OneDBarcodeReadOptions(); 
   // Show its values 
   ShowOptions("Default 2", options2); 
 
   // Load the previously saved options 
   options2.Load(xmlFileName); 
   // Show its values, should be the same as "New Options 1" 
   ShowOptions("Loaded 2", options2); 
} 
 
private static void ShowOptions(string message, OneDBarcodeReadOptions options) 
{ 
   // We will only show some of the options in this example 
   Console.WriteLine(message); 
   Console.WriteLine("  SearchDirection: {0}", options.SearchDirection);
