Document .Net - Import Element in mode KeepDifferentStyles

Import an Element with Styles.
Mode: KeepDifferentStyles

KeepDifferentStyles means to only copy styles that are different by formatting.
If the destination document already contains a style with the same name, therefore an unique style name will be generated.

For example, a destination document contains a style "MyGreen" (FontSize = 20, Green, Underline).

Destination:

And a source document also contains a style with the same formatting (FontSize = 20, Green, Underline), but a different name "Green" .

Let's import a 1st paragraph from the source document.
The paragraph contains text "Shrek" marked by the style "Green".
Because of the formatting of styles are equal, the "Green" style will not be imported.

Source:

(SourceStyles.docx)

After the importing, all imported elements linked to style "Green" will be remapped to the equal style "MyGreen":
