Here is a snippet of code I'd like you guys to comment. Basically my issue is that I have a multi-site-multi-lingual setup (think 2 websites, FR / EN). Bothsites have a search box, so basically, I end up with the following dictionaries:

- SiteA
    - SearchButton
- SiteB
    - SearchButton

Now I could simply prefix them SiteA_SearchButton. Even streamline that in my views. But here is the code I'm trying out, tell me what you think.

        /// <summary>
        /// Follows a trail of dictionary keys to find the one we want.
        /// Syntax: key1.key2.key3
        /// </summary>
        /// <param name="keys"></param>
        /// <param name="languageId"></param>
        /// <returns></returns>
        public static string GetDictionaryValue(string keys, int languageId) {

            var keyArray = keys.Split('.');

            // Starting point
            var dictionaryItem = new umbraco.cms.businesslogic.Dictionary.DictionaryItem(keyArray[0]);
            if (dictionaryItem == null)
            {
                // Can't find the starting point, return the last key of the array as a fallback behavior.
                return keyArray.LastOrDefault();
            }

            foreach(var key in keyArray.Skip(1)) {

                if (!dictionaryItem.hasChildren)
                {
                    break;
                }

                dictionaryItem = dictionaryItem.Children.FirstOrDefault(x => x.key == key);

                if (dictionaryItem == null)
                {
                    // Since we still have keys to find, but can't find the path, return the last key of the array as a fallback behavior.
                    return keyArray.LastOrDefault();
                }

            }

            // Return the corresponding value
            return dictionaryItem.Value(languageId);

        }

Then in my view: 

        <div id="search">
            <form method="get" action="@search.url">
                @{
                    var languageId = umbraco.cms.businesslogic.web.Domain.GetDomainsById(lang.Id)[0].Language.id;
                }
                <input type="text" id="search-input" name="s" placeholder="@Utilities.GetDictionaryValue("SiteA.SearchButton", languageId)" />
                <input type="submit" id="submit-search" value="" />
            </form>
        </div>

I think that languageId lookup could be better, but for the moment it's sufficient.

Basically the code allows be to navigate my dictionary items like this SiteA.SearchButton.

What do you guys think? Anything wrong here or to make better?

Thanks!
