Writes a block of bytes to the current stream using data read from a buffer.
Assembly: System.IO (in System.IO.dll)
The offset parameter gives the offset of the first byte in buffer to write from, and the count parameter gives the number of bytes to write. If the write operation is successful, the current position within the stream is advanced by the number of bytes written. If an exception occurs, the current position within the stream is unchanged.
Except for a MemoryStream constructed with a byte parameter, write operations at the end of a MemoryStream expand the MemoryStream.
