Parameters

path

String. The complete path of the file to be parsed.

stream

Stream. The stream to be parsed.

defaultEncoding

Encoding. The character encoding to use if encoding is not determined from file. Default is UTF8.

detectEncoding

Boolean. Indicates whether to look for byte order marks at the beginning of the file. Default is True.

leaveOpen

Boolean. Indicates whether to leave stream open when the TextFieldParser object is closed. Default is False.

reader

TextReader. The TextReader stream to be parsed.

Creates a new TextFieldParser object to parse the file or stream represented by the path, stream, or reader parameters.

If the defaultEncoding parameter is specified, this constructor uses it as the default encoding.

If the detectEncoding parameter is True, this constructor attempts to detect the encoding by looking at the first three bytes of the file or stream. It automatically recognizes UTF-8, little-endian Unicode, and big-endian Unicode text if the file starts with the appropriate byte-order marks. Otherwise, the encoding specified by defaultEncoding is used.

Caution noteCaution

When you compile a set of characters with a particular cultural setting and retrieve those same characters with a different cultural setting, the characters might not be interpretable and could cause an exception to be thrown.
