SpellCheck Class In Code Behind

Question

Is there a way to check spelling in code behind?

I only can find how to use it with UI control

<TextBox SpellCheck.IsEnabled="True" Height="20" Width="100"/>

What I want is boolean CheckSpell(string word)

I don't even need a suggested spelling.

This would used to determine the percentage of correctly spelled words in a text file.
A text file with a real low number was probably not intended for human consumption.

The app has SQL back end so loading a list of words in the Englich dictionary is an option.

To solve your problem you can use the NHunspell library.

Your check method in this case is very simple and looks like this:

bool CheckSpell(string word)
{         
    using (Hunspell hunspell = new Hunspell("en_GB.aff", "en_GB.dic"))
    {
        return hunspell.Spell(word);               
    }
}

You can find dictionaries on this site.

Also you can use SpellCheck class:

bool CheckSpell(string word)
{
    TextBox tb = new TextBox();
    tb.Text = word;
    tb.SpellCheck.IsEnabled = true;

    int index = tb.GetNextSpellingErrorCharacterIndex(0, LogicalDirection.Forward);
    if (index == -1)
        return true;
    else
        return false;
}
