TextFieldParser.EndOfData

Syntax

Dim fileParser As FileIO.TextFieldParser ' ...later... Dim result As Boolean = fileParser.EndOfData

Description

The EndOfData property indicates whether the parser has passed the final valid data record in the file (TRue) or not (False).

Usage at a Glance

• This property only considers valid record entries. If there are blank lines or other non-data lines between the current position and the true end of the file, those are ignored.

• You must close the TextFieldParser object when finished with it. Use the object's Close method or create the object instance with the Using keyword. See the TextFieldParser Object entry in this chapter for an example.

Example

The EndOfData property provides a convenient method to check for the end of the input data when parsing the entire contents of a file.

Dim fileParser As FileIO.TextFieldParser ' ...later... Do While Not fileParser.EndOfData ' ----- Read and process one record of data here. Loop fileParser.Close
