A task that represents the asynchronous operation. The value of the Result property contains the total number of bytes read into the buffer. The result value can be less than the number of bytes requested if the number of bytes currently available is less than the requested number, or it can be 0 (zero) if the end of the stream has been reached.
Exceptions
ExceptionCondition
ArgumentExceptionThe length of buffer is less than offset plus count.
