Case insensitive access for generic dictionary

Question

I have an application that use managed dlls. One of those dlls return a generic dictionary:

Dictionary MyDictionary;  

Answer 1

Its not very elegant but in case you cant change the creation of dictionary, and all you need is a dirty hack, how about this:

var item = MyDictionary.Where(x => x.Key.ToLower() == MyIndex.ToLower()).FirstOrDefault();
    if (item != null)
    {
        TheValue = item.Value;
    }
