TextReader.Close Method

Closes the TextReader and releases any system resources associated with the TextReader.

[Visual Basic]
Public Overridable Sub Close()
[C#]
public virtual void Close();
[C++]
public: virtual void Close();
[JScript]
public function Close();

Remarks

This implementation of Close calls the Dispose method passing a true value.

Flushing the stream will not flush its underlying encoder unless you explicitly call Close. Setting AutoFlush to true means that data will be flushed from the buffer to the stream, but the encoder state will not be flushed. This allows the encoder to keep its state (partial characters) so that it can encode the next block of characters correctly. This scenario affects UTF8 and UTF7 where certain characters can only be encoded after the encoder receives the adjacent character or characters.

Following a call to Close, any operations on the TextReader might throw exceptions. This default method is empty, but derived classes can override the method to provide the appropriate functionality.
