Umbraco 7 - Update dictionary item's value via code

Question

There's Umbraco's Dictionary section which contains all its items.
I'm trying to find a way to update the value of a specific item via my code (.NET).
I know how can I get the value, but don't know how to set and update it.
Any recommendations?

If you are using Umbraco's LocalizationService to create your dictionary items and get them programmatically, then this is how you update an existing dictionary item's value;

// Get the existing dictionary item to delete it
var dictionaryItem = _localizationService.GetDictionaryItemByKey(data.Key);
    
// Get all languages
var allActiveLanguages=_localizationService.GetAllLanguages();
                        
// Set your language - I only have one language, which is why I'm getting the first one here
var language = allActiveLanguages.FirstOrDefault();
    
                        
if (language != null)
{
 _localizationService.AddOrUpdateDictionaryValue(dictionaryItem, language, "New dictionary value is here!!");
}

// Save your updates    
_localizationService.Save(dictionaryItem);

PS: Below image is how you can use the ILocationService.
