If this method throws an OutOfMemoryException exception, the reader's position in the underlying Stream object is advanced by the number of characters the method was able to read, but the characters already read into the internal ReadLine 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 to produce robust code, you should use the KeyAvailable property and ReadKey method and store the read characters in a pre-allocated buffer.
