Does it use Microsoft Word's spellchecker?
Thank you.
回答1:
No, they are not part of Microsoft Word. They are part of WPF. It would be an inconvenience to developers to have a feature dependent on a Microsoft Word installation. Instead, it uses an embedded dictionary.
WPF4 introduced functionality for custom dictionaries.

You didn't mention what you need it for.
So here is a wild guess. You may want to check out: http://nhunspell.sourceforge.net/
NHunspell brings the spell checking, hyphenation and thesaurus to the Microsoft® .NET Framework. NHunspell is C# library and wraps native libraries for Hunspell, Hyphen and MyThes. One design goal of this library and wrapper is to keep the source code of the included libraries as unmodified as possible. New versions of the base libraries can therefore easily adopted to NHunspell. The integrated libraries are used in OpenOffice and they work with the dictionaries published on OpenOffice.org.
