byteobject (the read buffer).
To read the field value,
ReadBytes should be successively called until it returns a value less than the length of the read buffer. The value of the bytes in the buffer following the last byte read is undefined.
ReadBytes returns a value equal to the length of the buffer, a subsequent
ReadBytes call must be made. If there are no more bytes to be read, this call returns -1.
If the byte array field value is null,
ReadBytes returns -1.
If the byte array field value is empty,
ReadBytes returns 0.
Once the first
ReadBytes call on a
byte field value has been made, the full value of the field must be read before it is valid to read the next field. An attempt to read the next field before that has been done will throw a
To read the byte field value into a new
byte object, use the
the total number of bytes read into the buffer, or -1 if there is no more data because the end of the byte field has been reached
