Multiple parameters in a List. How to create without a class?

This is probably a pretty obvious question, but how would I go about creating a List that has multiple parameters without creating a class.

Example:

var list = new List<string, int>();

list.Add("hello", 1);

I normally would use a class like so:

public class MyClass
{
    public String myString {get; set;}
    public Int32 myInt32 {get; set;}
}

then create my list by doing:

var list = new List<MyClass>();
list.Add(new MyClass { myString = "hello", myInt32 = 1 });

If you are using .NET 4.0 you can use a Tuple.

List<Tuple<T1, T2>> list;

For older versions of .NET you have to create a custom class (unless you are lucky enough to be able to find a class that fits your needs in the base class library).

If you do not mind the items being imutable you can use the Tuple class added to .net 4

var list = new List<Tuple<string,int>>();
list.Add(new Tuple<string,int>("hello", 1));

list[0].Item1 //Hello
list[0].Item2 //1

However if you are adding two items every time and one of them is unique id you can use a Dictionary

If appropriate, you might use a Dictionary which is also a generic collection:

Dictionary<string, int> d = new Dictionary<string, int>();
d.Add("string", 1);
