Data type. Multi pair of values. How can I do this?

[shapper]

Hello,

I need to pass to a function a list of pairs of values.

For each item the first value is a string and the second value is an
Enum named Country.

For example, consider I need to pass 3 items:

"New York", Country.UnitedStates

"Paris", Country.France

"London", Country.England

What data type should I use create this?

And how can I access each item inside my function?

Thanks,

Miguel

You could use a struct for this. Something like

public struct CityInfo
{
string name;
Country countryCode;
}

and then

CityInfo ny = new CityInfo();
ny.name = "New York";
ny.countryCode = Country.UnitedStates;

Structs are good when you need lightweight objects, like here for
logical grouping of attributes. Note however that contrarily to classes,
structs are value types, not reference types.
