inbuilt Data Structure in C#, which can hold pair like Key, Value, Value

Question

I am looking for a inbuilt Data Structure in C#, which can hold pair like Key, Value, Value.

For Example for Dictionary in C# we have Key and Value. Similarly I am Looking a inbuilt data structure, which holds Key, Value, Value. It should be generic.

`Dictionary` and expose two `Value` properties in `MyCustomClass` — , Sep 10 '15 at 11:06

How about Tuple<T1, T2, T3>?

It even supports up to 8 values.

but this doesn't force the value for T1 to be unique – simonalexander2005 Sep 10 '15 at 11:17

He gave the dictionary as example. And such a data structure could never force the value to be unique. That has to be done by the containing data structure – Domysee Sep 10 '15 at 11:20

he did ask for "Key, Value, Value" though; as opposed to "Value, Value, Value" – simonalexander2005 Sep 10 '15 at 11:24
A key is nothing more than a value, just with a different meaning. If you define T1 to be a key in your application, then it is a key. – Domysee Sep 10 '15 at 11:27
He was also asking for one data structure that can handle this case, and tuple is the only one that can without nesting classes – Domysee Sep 10 '15 at 11:28
that's fair - we'll see if the OP clarifies then :) – simonalexander2005 Sep 10 '15 at 11:31
Thanks Domysee for your input :-). – Ashish Nov 20 '15 at 08:19

Dictionary<T1, Tuple<T2, T3>> works, as @Mant101 said in the comments. or Dictionary<T1, KeyValuePair<T2, T3>> if there is also a key-value relationship between T2 and T3

KeyValuePair is not good unless there really is a key/value relationship between T2 and T3. – Sebastian Negraszus Sep 10 '15 at 11:41
