Mixed type Dictionary

[DonJefe]

Is there any way to have a mixed type Dictionary object? For example
something like:
dictionary.Add(3, "foobar");
dictionary.Add("foo", 33444);

I am trying to make a generic parameter list without reverting to
Dictionary<object, object>. Any ideas on where to look for this sort of
thing? I have been doing a lot of work with generics lately, but have
not found anything to fit the bill.

Thanks.

Well, it is hard to do without boxing... but can be done...

Look at the following; you can (as examples);

ParameterSet ps = new ParameterSet();
ps.Add("Test", 5);
ps.Add<int>("SomeParam");
int val = ps.GetValue<int>("Test");
ps.SetValue("SomeParam", 17);
IParameter param = ps["Test"];
param.Type...
param.Value...
param.Name...

etc
