Write() public method

When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written.
public Write ( byte buffer, int offset, int count ) : void
buffer byte /// An array of bytes. This method copies bytes from /// /// to the current stream. ///
offset int /// The zero-based byte offset in at which to begin copying bytes to the /// current stream. ///
count int The number of bytes to be written to the current stream.
return void
