Description
Reads and returns a 64-bit integer from the reader object's stream.
ReadInt64 is a helper method used by other reader methods to read a tagged 64-bit integer Int64 value at the current reader Position.
ReadInt64 calls ReadValue to check whether the value-type indicator is vaInt64, and then ReadInt64 calls Read and returns the Int64 integer value. Otherwise, ReadInt64 returns the stream position back before the value-type indicator, calls ReadInteger, in case the value was saved in another integer format and returns the retrieved value.
ReadInt64 advances the reader Position after the last byte it has read.
