Вот несколько примеров чтения / записи
' read a record "2"
Dim ar_record As UniDynArray = nepiLicenceStatusFile.Read("2")
' write back as record "2new"
nepiLicenceStatusFile.Read("2new", ar_record)
' write a random string to a record
nepiLicenceStatusFile.write("2new", "My random string")
'read a field "7" from record "2"
Dim ar_record2 As UniDynArray = nepiLicenceStatusFile.ReadField("2", 7)
' write back to field "8"
nepiLicenceStatusFile.write("2", 8)
'read number of fields (4,5,6) from record "2"
Dim lFieldSet() As Integer = {4, 5, 6}
Dim ar_record3 As UniDynArray = nepiLicenceStatusFile.ReadFields("2", lFieldSet)
' read named field "LNAME" from record "2"
Dim ar_record4 As UniDynArray = nepiLicenceStatusFile.ReadNamedField("2", "LNAME")
' read records (2, 12, 3 and 4) as unidataset
Dim sArray As String() = {"2", "12", "3", "4"}
uSet = nepiLicenceStatusFile.ReadRecords(sArray)
