Read() public method

Reads a block of bytes from the current stream and writes the data to buffer.
is null. /// or is less than 0 -or- /// and will exceed length. /// The stream is closed.
public Read ( byte buffer, int startIndex, int length ) : int
buffer byte When this method returns, contains the specified byte array with the values between and ( + - 1) replaced by the characters read from the current stream.
startIndex int The byte offset in at which to begin reading.
length int The maximum number of bytes to read.
