.NET Spell Check control?
Are there any libraries out there (preferably a self contained Text Edit Control) for .NET that have Spell Check capabilities. I would like to add the typical red underline to miss-spelled words in the edit area of my application.
Edit: To clarify, this is for WinForms
Answer
Aspell.Net looks nice, but does not seem to be maintained anymore. I could not get it to work on my machine.
After searching around SourceForge, I found NHunspell, which is a .Net port of the spell checker from OpenOffice.org. It provides methods to spell check, find synonyms, and hyphenate. Its actively maintained at this time, and comes with easy to understand sample code.
In the project's own words:
Spell Checker, Hypenation and Thesaurus: NHunspell
NHunspell is a free open source spell checker for the .NET Framework. C# and Visual Basic sample code is available for spell checking, hyphenation and synonym lookup via thesaurus.
NHunspell is based on Hunspell and brings the Open Office spell checking, hyphenation and thesaurus to the Microsoft® .NET Framework. NHunspell is a .NET (C#, VB) library and wraps the native libraries Hunspell, Hyphen and MyThes.
The integrated libraries are used in OpenOffice and work with the dictionaries published on OpenOffice.org. License
