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

public virtual string ReadToEnd()

Return Value

Type: System..::..String
A string that contains all characters from the current position to the end of the text reader.

If the method throws an OutOfMemoryException exception, the reader's position in the underlying Stream is advanced by the number of characters the method was able to read, but the characters that were already read into the internal ReadToEnd buffer are discarded. Because the position of the reader in the stream cannot be changed, the characters that were 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.
