如何将拼写检查器添加到Richtext框中？

Question

如何在我的应用程序中的RichTextBox中添加拼写检查器？

Answer 1

You can purchase a spell checker control, integrate the Microsoft Office Spell Checker, write your own (which isn't too hard, actually, once you get the Soundex function figured out), or get a good free one. Here's a (relatively) good free one.

For commercial products, I'd say to Google "Spell check WinForms"

If you're interested in rolling your own, I wrote one for Asp.Net back when I was in my beginner phase, and even then it only took me about a week to research and then a day or so to code. It's a fun pet project. I'd start by looking at soundex functions and comparing soundex values for similarity.

You start by comparing all of the words in the TextBox to a known dictionary, and using the soundex functions to come up with similar words.

From there, you can go on to creating a table for "popular replacements. (for example, you can track that the word "teh" was replaced by "the" n times and move the more popular replacements to the top of the list.

I found a better solution. Hunspell is the spellcheck library Mozilla and OpenOffice.org uses. Its been ported to .NET as NHunspell , and is real easy to implement and has samples for you to use.
