How can I access string values in Results View where the number of results may vary?

Question

How can I access the string values in IEnumerable Results View, where the results may vary?

I am using a foreach loop to iterate through a list, and then grabbing the distinct values of VehicleID:

foreach (var trip in paidTrips) {
    var vehicleids = trip
        .Select(x => x.VehicleID)
        .Distinct()
        .ToList();

I know how to do this:

string n = vehicleids[0];
string o = vehicleids[1];

But that gives me an "Index was out of range"-exception if there's more than two items.

I am thinking it would be good to use a for loop to iterate through the indexes and create an array out of them? If so, how could I do that?

Answer 1

try this

IEnumerable<string> vehicleIds=paidTrips
        .Select(x => x.VehicleID)
        .Distinct()
        .ToList();
        //or ToArray();

you can acces using foreach loop

foreach( var id in vehicleIds)
{
       Console.WriteLine(id);
}

or just using index

var vehicleId0 = vehicleids[0];
//or 
var vehicleId1=vehicleId[1];

or using linq

var vehicleId=vehicleIds.FirstOrDefault(x=> x=="1223");
