HexView

- Inherited Members
Remarks
HexView provides a hex editor on top of a seekable Stream with the left side showing an hex dump of the values in the Stream and the right side showing the contents (filtered to non-control sequence ASCII characters).
Users can switch from one side to the other by using the tab key.
To enable editing, set AllowEdits to true. When AllowEdits is true the user can make changes to the hexadecimal values of the Stream. Any changes are tracked in the Edits property (a SortedDictionary<TKey, TValue>) indicating the position where the changes were made and the new values. A convenience method, ApplyEdits(Stream) will apply the edits to the Stream.
Control the first byte shown by setting the DisplayStart property to an offset in the stream.
