LinkarClt lkClt = new LinkarClt();
CredentialsOptions crdOpt = new CredentialsOptions("127.0.0.1", 11300, "admin", "admin", "ENTRYPOINT");
lkClt.Login(crdOpt);

string filename = "LK.CUSTOMERS";
string recordId = "99";
DeleteOptions deleteOptions = new DeleteOptions();
string originalRecord = ""; // Buffer with the original record content (only necessary for use with optimistic lock control)
LkData lkDataDelete = lkClt.Delete(filename, recordId, deleteOptions, originalRecord);
