Summary

Represents a writer that can write a sequential series of characters.

Description

TextWriter is designed for character output, whereas the Stream class is designed for byte input and output.

[Note: By default, a TextWriter is not thread safe. See System.IO.TextWriter.Synchronized(System.IO.TextWriter) for a thread-safe wrapper. ]

TextWriter.Close Method

public virtual void Close();

Summary

Closes the current TextWriter instance and releases any system resources associated with it.

Description

[Note: After a call to System.IO.TextReader.Close , any operation on the current instance might throw an exception.

This version of System.IO.TextReader.Close is equivalent to System.IO.TextReader.Dispose(System.Boolean)(true ).

TextWriter.Dispose Method

protected virtual void Dispose(bool disposing);

Summary

Releases the unmanaged resources used by the TextWriter and optionally releases the managed resources.

Parameters

disposing
true to release both managed and unmanaged resources; false to release only unmanaged resources.

Description

When the disposing parameter is true , this method releases all resources held by any managed objects that this FileStream references. This method invokes the Dispose() method of each referenced object.

[Note: System.IO.FileStream.Dispose(System.Boolean) may be called multiple times by other objects. When overriding System.IO.FileStream.Dispose(System.Boolean)(Boolean), be careful not to reference objects that have been previously disposed in an earlier call to System.IO.FileStream.Dispose(System.Boolean) .]

TextWriter.NewLine Property

public virtual string NewLine { get; set; }

Summary

Gets or sets the line terminator string used by the current TextWriter .

Property Value

A String containing the line terminator string for the current TextWriter .

Description

The default line terminator string is System.Environment.NewLine .

The line terminator string is written to the text stream whenever one of the System.IO.TextWriter.WriteLine methods is called. In order for text written by the TextWriter to be readable by a TextReader , only "\n" or System.Environment.NewLine should be used as terminator strings. If System.IO.TextWriter.NewLine is set to null , the default newline character is used instead.
