Writes a block of bytes to the current stream using data read from a buffer.
Assembly: mscorlib (in mscorlib.dll)
buffer is null.
The stream does not support writing. For additional information see CanWrite.
The current position is closer than count bytes to the end of the stream, and the capacity cannot be modified.
offset subtracted from the buffer length is less than count.
offset or count are negative.
An I/O error occurs.
The current stream instance is closed.
This method overrides Write.
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.
