Question

I need something resembling the following:

Dictionary<string, List<int>, List<DateTime>> = 
             new Dictionary<string, List<int>, List<DateTime>>()

are there any built in class in C# which offer something like the above?

Edit: for people who can’t see why anything like this could ever possibly be useful…

Imagine if you could write something like this:

mySuperDictionary SuperDictionary<string, List<int>X, List<int>Y> .....

myXvalues = mySuperDictionary["myKey"].X;
myYvalues = mySuperDictionary["myKey"].Y;

personally I think that would be a pretty neat.

Answer 1

No.

Create a Pair or Tuple type yourself.

Something like:

class Pair<T,V>
{
  T First{get; set;}
  V Second{get; set;}
}

Then you can declare a Dictionary<string, Pair<List<int>, List<DateTime>>.
