Dictionary与结构体、委托的结合

用字典存储多个对象

        Dictionary<string, (Type onEntity, Type onJson)> dic = new Dictionary<string, (Type typ1, Type typ2)>
        {
            {"key", (typeof(int), typeof(string))}
        };

在字典中存储委托

public class Container
{
    private delegate string IntToStr(int i);
    private delegate TResult LeftToRight<TArg, TResult>(TArg left);
    Dictionary<string, Delegate> dic = new Dictionary<string, Delegate>();

    public Container()
    {
        Func<int, string> dlg_1 = (i) => { return i.ToString(); };
        dic.Add("key1", dlg_1);
        dic.Add("key2", (Func<int, string>)((i) => { return i.ToString(); }));

        IntToStr dlg_2 = (i) => { return i.ToString(); };
        dic.Add("key3", dlg_2);
        dic.Add("key4", (IntToStr)((i) => { return i.ToString(); }));

        LeftToRight<int, string> dlg_3 = (left) => { return left.ToString(); };
        dic.Add("key5", dlg_3);
        dic.Add("key6", (LeftToRight<int, string>)((left) => { return left.ToString(); }));
    }
}
