Assembly: Microsoft.Office.Interop.Word (in microsoft.office.interop.word.dll)
Use the HangulHanjaDictionaries property to return the collection of currently active custom conversion dictionaries.
Use the Add method to add a new custom conversion dictionary to the collection of active custom conversion dictionaries. If there isn't a file with the name specified by FileName, Microsoft Word creates it.
Use the ClearAll method to unload all custom conversion dictionaries. Note, however, that this method doesn't delete the dictionary files. After you use this method, the number of custom conversion dictionaries in the collection is 0 (zero).
You set the custom dictionary to which new words are added by using the ActiveCustomDictionary property. If you try to set this property to a dictionary that isn't a custom conversion dictionary, an error occurs.
The Maximum property returns the maximum number of simultaneous custom conversion dictionaries that the application can support. For Word, this maximum is 10.
