This is a non-GUI component, suitable for the business/logic layer of your application. You would use this component in web server based applications. This component can be used in 2 different ways. The most common usage, in an iterative fashion is detailed below, but it may also be used on a query by query basis. To use this component in an iterative way you must first call Check to set the text to check and then iterate through NextBadWord() to identify misspelt words. NextBadWord will return a BadWord object and internally locate the the misspelt word in the text, then you can call FindSuggestions which will return a ArrayList of suggestions as String objects. You may also call ChangeBadWord(replacement) to replace that current misspelt word in the text. NextBadWord() will return null when the text has been checked. GetAmendedText returns the current state of the text with corrections. Calling ChangeBadWord or FindSuggestions before NextBadWord has been called and returned a BadWord (i.e. not null) will result in a NoCurrentBadWordException.

The second way to use this component is simply to query words yourself using LookUp(word) to check if word is in the lexicon/dictionary and FindSuggestions(word) to find spelling suggestions for word.

Check some text, find suggestions and replace mis-spelt words with "replacement".

CopyC#

RapidSpellChecker c = new RapidSpellChecker(); 
BadWord badWord; 
ArrayList suggestions; 

 //check some text.  
c.Check("This is sume text."); 

//iterate through all bad words in the text.  
while((badWord = c.NextBadWord())!=null){ 

    Console.WriteLine(badWord.GetWord() + "- is not spelt correctly. Suggestions:"); 

    try{ 
        //get suggestions for the current bad word.  
        suggestions = c.FindSuggestions(); 

        //display all suggestions.  
        for(int i=0; i<suggestions.Count; i++){
            Console.WriteLine(suggestions[i]);
        }

        //change the bad word in the text with "replacement".  
        c.ChangeBadWord("replacement"); 

    } catch (NoCurrentBadWordException e){ 
        Console.WriteLine(e); 
    } 

} 
Console.WriteLine(c.GetAmendedText());
