Question

I have set up a configuration system that will grab the configuration from a MySQL database. And I have got it working, but now I realize that to get the Value from the Cache, I have to use this long messy code.

CacheLayer.Instance.Caches["app_config"].Current.EmailALertInterval

I would like to remove Current, but I haven’t managed to figure out if it’s possible to have the class do this directly. At the moment the implementation looks like this.

public T Current
{
    get
    {
        if (_current == null)
        {
            ReloadConfiguration();
        }

        return _current;
    }
}

But I would like to simply it to this:

CacheLayer.Instance.Caches["app_config"].EmailALertInterval

I am looking at something like this, but this only works with indexers.

public T this[T key]

EDIT: Just to add some more context I will add some more code.

This is CacheLayer. It essentially allows me to store multiple configurations. I may have one that is for example the general app config, but I can also grab an array of Emails used.

public Dictionary<String,IGenericCache<dynamic>> Caches
{
    get
    {
        return _caches;
    }
}

public void AddCache(String config)
{
    _caches.Add(config,new GenericCache<dynamic>(config));
}

Inside my GenericCache I load the configuration using a JSON string stored in a MySQL db.

_current = JsonConvert.DeserializeObject<T>(db.dbFetchConfig(config));

The reason that GenericConfig is T and not dynamic is because I want to be able to make a custom implmentation outside of the CacheLayer, one that does not necessarily use dynamic.

ANother example on how I want this to be used.

List<String> EmailList = CacheLayer.Instance.Caches["EmailList"].Current;

This would in fact grab an JSON Array from the MySQL containing a list of Emails.

Any ideas?

Add a new property

public int EmailALertInterval
{
    get { return Current.EmailALertInterval; }
}
