The CanRead, CanSeek, and CanWrite properties are all set to true, but the capacity cannot be changed. Capacity is set to count.

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. However, you can write to the stream.
