How to determine if a string contains any matches of a list of strings

Question

Hi say I have a list of strings:

var listOfStrings = new List<string>{"Cars", "Trucks", "Boats"};

and I have a vehicles options which has a Name field.

I want to find the vehicles where the name matches one of the items in the listOfStrings.

I'm trying to do this with linq but can't seem to finish it at the moment.

var matchingVehicles = Vehicles.Where(v => v.Name == one of the listOfStringItem)

Can anybody help me with this?

Answer 1

Vehicles.Where(v => listOfStrings.Contains(v.Name))

Answer 2

Use a HashSet instead of a List, that way you can look for a string without having to loop through the list.

var setOfStrings = new HashSet<string> {"Cars", "Trucks", "Boats"};

Now you can use the Contains method to efficiently look for a match:

var matchingVehicles = Vehicles.Where(v => setOfStrings.Contains(v.Name));

Answer 3

would this work:

listOfStrings.Contains("Trucks");
