Parameters

buffer

The byte array from which to create the new stream. [Edit]

Exceptions

Type	Reason
ArgumentNullException	The buffer parameter is null. [Edit]

Remarks

The Stream.CanRead, Stream.CanSeek, and Stream.CanWrite properties of the new instance of the System.IO.MemoryStream class are set to true. MemoryStream.Capacity is set to the length of the specified byte array.

Note: The new stream instance can be written to, but the MemoryStream.Capacity of the underlying byte array cannot be changed. The length of the stream cannot be set to a value greater than MemoryStream.Capacity , but the stream can be truncated (see MemoryStream.SetLength(long)).

The new stream does not expose the underlying byte buffer, and calls to the MemoryStream.GetBuffer method throw UnauthorizedAccessException.
