BinaryReader.Close Method

Closes the current reader and the underlying stream.

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)

public virtual void Close ()
public void Close ()
public function Close ()
Not applicable.

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.

This code example is part of a larger example provided for the BinaryReader class.

BinaryReader binReader =
    new BinaryReader(File.Open(fileName, FileMode.Open));
try
{
    // If the file is not empty,
    // read the application settings.
    // Read 4 bytes into a buffer to
    // determine if the file is empty.
    byte[] testArray = new byte[3];
    int count = binReader.Read(testArray, 0, 3);

    if (count != 0)
    {
        aspectRatio   = binReader.ReadSingle();
        lookupDir     = binReader.ReadString();
        autoSaveTime  = binReader.ReadInt32();
        showStatusBar = binReader.ReadBoolean();
    }
}

// If the end of the stream is reached before reading
// the four data values, ignore the error and use the
// default settings for the remaining values.
catch(EndOfStreamException e)
{
    Console.WriteLine("{0} caught and ignored. " +
        "Using default values.", e.GetType().Name);
}
finally
{
    binReader.Close();
}

BinaryReader binReader =
    new BinaryReader(File.Open(fileName, FileMode.Open));
try {

    // If the file is not empty,
    // read the application settings.
    // Read 4 bytes into a buffer to
    // determine if the file is empty.
    ubyte[] testArray = new ubyte[3];
    int count = binReader.Read(testArray, 0, 3);
    if (count != 0)
    {
        aspectRatio = binReader.ReadSingle();
        lookupDir = binReader.ReadString();
        autoSaveTime = binReader.ReadInt32();
        showStatusBar = binReader.ReadBoolean();
    }
}

// If the end of the stream is reached before reading
// the four data values, ignore the error and use the
// default settings for the remaining values.
catch(EndOfStreamException e) {
    Console.WriteLine("{0} caught and ignored. "
        + "Using default values.", e.GetType().get_Name());
}
finally {
    binReader.Close();
}
