How to: Add Dictionaries from an Assembly Resource

The code sample below shows how to use the GetExecutingAssembly() and GetManifestResourceInfo(String) methods to deploy dictionaries in the application’s assembly.

The LoadFromStream(Stream, Stream, Stream) method allows you to load dictionary files from a stream.

When you load dictionaries from assembly resources, make sure that the dictionary files’ Build Action property is set to Embedded Resource.


The complete sample project is available at How to load a spellchecker dictionary from an assembly resource repository on GitHub.

private void Form1_Load(object sender, EventArgs e)
    //Create a new dictionary instance
    SpellCheckerISpellDictionary dictionary = new SpellCheckerISpellDictionary();

    //Create stream objects for each dictionary file
    Stream affStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("WindowsApplication27.Dictionaries.english.aff");
    Stream dicStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("WindowsApplication27.Dictionaries.american.xlg");
    Stream alphStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("WindowsApplication27.Dictionaries.EnglishAlphabet.txt");

    //Load files to the dictionary
    dictionary.LoadFromStream(dicStream, affStream, alphStream);

    //Add dictionary to the spell checker collection
