Once you have created your credit note, you need to call the process method, which returns the credit note number, as shown below

 Customer lvCUstomer = new Customer("00001");
 CreditNote cn = new CreditNote();
 cn.Customer = lvCUstomer;
 ...
 cn.Save();
 OrderDetail cNoteDetail = new OrderDetail();
 cn.Detail.Add(cNoteDetail);
 
GLAccount detailGL = new GLAccount("1000101");
cNoteDetail.GLAccount = detailGL;
cNoteDetail.Project = proj;
cNoteDetail.TaxType = new TaxRate("13");
cNoteDetail.Quantity = 1;
cNoteDetail.ToProcess = 1;
cNoteDetail.UnitSellingPrice = 199.99;
cNoteDetail.Discount = 0;
cNoteDetail.Description = "CNote Description";

cn.Save();
String lvCreditNoteNo = cn.Process();

you can then do what you wish with the credit note number
