function Read(buffer, startIndex, length);Parameters
- buffer Byte
- When this method returns, contains the specified byte array with the values between startIndex and (startIndex + length - 1) replaced by the characters read from the current stream.
- startIndex Int32
- The byte offset in buffer at which to begin reading.
- length Int32
- The maximum number of bytes to read.
