Create Tuple with more than 2 arguments

Question

I want to convert

List<Tuple<IntPtr, string, string>>

into

Dictionary<IntPtr, Tuple<string,string>>

using

ToDictionary

ie

var T = new List<Tuple<IntPtr, string, string>>();
T.ToDictionary(/*I cannot figure out the right syntax*/);

All examples I could find have just 2 arguments while I have 3.

Answer 1

You should use Enumerable.ToDictionary overload which accepts both key and value selectors:

T.ToDictionary(t => t.Item1, t => Tuple.Create(t.Item2, t.Item3))

But keep in mind, that there should not be duplicated pointers in your list.
