Question

The class looks as follows:

public static class CacheManager
{
    private static Dictionary<string, object> cacheItems = new Dictionary<string, object>();

    private static ReaderWriterLockSlim locker = new ReaderWriterLockSlim();

    public static Dictionary<string, object> CacheItems
    {
        get
        {
            return cacheItems;
        }
    }
    ...
}

The ReaderWriterLockSlim locker object should be used as well.

The client looks as follows now:

foreach (KeyValuePair<string, object> dictItem in CacheManager.CacheItems)
{
    ...
}

Thank you in advance.

If you only need to iterate the contents, then frankly it isn’t really being used as a dictionary, but an iterator block and indexer might be used to hide the internal object:

public IEnumerable<KeyValuePair<string, object>> CacheItems
{
    get
    { // we are not exposing the raw dictionary now
        foreach(var item in cacheItems) yield return item;
    }
}
public object this[string key] { get { return cacheItems[key]; } }
