BinaryWriter.Close Method

Closes the current BinaryWriter and the underlying stream.

[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 Flush or 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.

Example

[Visual Basic, C#, C++] This code example is part of a larger example provided for the BinaryWriter class.

[Visual Basic] 
Dim binWriter As New BinaryWriter( _
    File.Open(fileName, FileMode.Create))
Try
    binWriter.Write(aspRatio)
    binWriter.Write(lkupDir)
    binWriter.Write(saveTime)
    binWriter.Write(statusBar)
Finally
    binWriter.Close()
End Try

[C#] 
using(BinaryWriter binWriter = 
    new BinaryWriter(File.Open(fileName, FileMode.Create)))
{
    binWriter.Write(aspectRatio);
    binWriter.Write(lookupDir);
    binWriter.Write(autoSaveTime);
    binWriter.Write(showStatusBar);
}

[C++] 
BinaryWriter* binWriter = 
    new BinaryWriter(File::Open(fileName, FileMode::Create));
try
{
    binWriter->Write(aspectRatio);
    binWriter->Write(lookupDir);
    binWriter->Write(autoSaveTime);
    binWriter->Write(showStatusBar);
}
__finally
{
    binWriter->Close();
}
