Func and List<string>

I have defined the following

Dictionary<string, Func<string, List<string>>> test1 = new Dictionary<string, Func<string, List<string>>>();

also I have

    private string fred(List<string> Parms)
    {

        return "Tes开发者_如何学Pythont";
    }

how do I add fred to the dictionary? I have tried

       test1.Add("Test",fred);

but I get an error, if I replace the List for a string everything is ok.

You have the arguments around the wrong way. A Func<X,Y> takes an X and returns a Y. Your dictionary should be:

Dictionary<string, Func<List<string>,string>>

Dictionary<string, Func<string, List<string>>> test1 = new Dictionary<string, Func<string, List<string>>>();

should be

Dictionary<string, Func<List<string>, string>>> test1 = new Dictionary<string, Func<List<string>, string>>();
