The CanRead, CanSeek, and CanWrite properties are all set to true. Capacity is set to the length of the specified byte array. The new stream can be written to, but is not resizable.
The length of the stream cannot be set to a value greater than the initial length of the specified byte array; however, the stream can be truncated (see SetLength).
This constructor does not expose the underlying stream. GetBuffer throws UnauthorizedAccessException.
