TextReader and TextWriter

These are stream helper classes that make it easier to read and write text data onto an underlying stream. The following table describes the TextReader class’s most useful methods.

Open table as spreadsheet

Method	Purpose
Close	Closes the reader and releases any resources that it is using.
Peek	Reads the next character from the text without changing the reader’s state so other methods can read the character later.
Read	Reads data from the input. Overloaded versions of this method read a single character, or an array of characters up to a specified length.
ReadBlock	Reads data from the input into an array of characters.
ReadLine	Reads a line of characters from the input and returns the data in a string.
ReadToEnd	Reads any remaining characters in the input and returns them in a string.

The following table describes the TextWriter class’s most useful properties.
