If the current method throws an OutOfMemoryException, the reader's position in the underlying Stream is advanced by the number of characters the method was able to read, but the characters already read into the internal ReadToEnd buffer are discarded. Since the position of the reader in the stream cannot be changed, the characters already read are unrecoverable, and can be accessed only by reinitializing the TextReader. If the initial position within the stream is unknown or the stream does not support seeking, the underlying Stream also needs to be reinitialized.

To avoid such a situation and produce robust code you should use the Read method and store the read characters in a preallocated buffer.

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

Shared Sub ReadText(aTextReader As TextReader)
    Console.WriteLine("From {0} - {1}", _
        aTextReader.GetType().Name, aTextReader.ReadToEnd())
End Sub

static void ReadText(TextReader textReader)
{
    Console.WriteLine("From {0} - {1}", 
        textReader.GetType().Name, textReader.ReadToEnd());
}

void ReadText( TextReader^ textReader )
{
   Console::WriteLine( "From {0} - {1}", textReader->GetType()->Name, textReader->ReadToEnd() );
}
