int aFieldNumber is the number of the field to which data is to be written. If you do not specify aFieldNumber, this method writes to field 1.

UniDynArray aRecordData or string aRecordData is the field value to be written to the record. If you do not specify aRecordData, the field value to be written is the one set previously by the Record property.

string aRecordID is the ID of the record to which the data is to be written. If you do not specify aRecordID, the record ID is the one set previously by the RecordID property.

After executing the Write Field( ) method, call the FileStatus property to determine the state of record locks during the operation, as follows:

If this method fails, it throws a UniFileException.

This method corresponds to the UniObjects WriteField method and the BASIC WRITEV and WRITEVU statements.

This example writes the string NewFieldValue into field 3 of the record REC3.

int fieldnumber = 5;
string  recID = “2”;
UniDynArray arr = new UniDynArray(us,”abc”);
fl.WriteField(recID, fieldnumber ,arr);
