Important edit : Do not use a Dictionary in this context. It uses Object.GetHashCode() which isn't good for use as a dictionary key. I still learned something from this though.
I have the following declaration
private static IDictionary<IDictionary<string,string>, IEnumerable<Fishtank>> _cache;
and the following code to attempt to initialize it
if (_cache == null)
_cache = new Dictionary<Dictionary<string,string>, LinkedList<Fishtank>>();
The problem I'm having is the initialization generates a compile time error.
Cannot implicitly convert type 'System.Collections.Generic.Dictionary,System.Collections.Generic.LinkedList>' to 'System.Collections.Generic.IDictionary,System.Collections.Generic.IEnumerable>'. An explicit conversion exists (are you missing a cast?)
I know that Dictionary and LinkedList implement IDictionary and IEnumerable respectively, so I'm at a bit of a loss here.
you can do as below
if (_cache == null)
_cache = new Dictionary<IDictionary<string, string>, IEnumerable<Fishtank>>();
