MemoryStream.Write Method

July 28, 2014

Writes a block of bytes to the current stream using data read from a buffer.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Overrides Sub Write ( _
	buffer As Byte(), _
	offset As Integer, _
	count As Integer _
)

Parameters

buffer
Type: System.Byte ()
The buffer to write data from.
offset
Type: System.Int32
The zero-based byte offset in buffer at which to begin copying bytes to the current stream.
count
Type: System.Int32
The maximum number of bytes to write.

ExceptionCondition
ArgumentNullException

buffer is Nothing.

NotSupportedException

The stream does not support writing. For additional information see CanWrite.

-or-

The current position is closer than count bytes to the end of the stream, and the capacity cannot be modified.

ArgumentException

offset subtracted from the buffer length is less than count.

ArgumentOutOfRangeException

offset or count are negative.

IOException

An I/O error occurs.

ObjectDisposedException

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.
