C# How to make a list out of IEnumerable

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'm currently playing with TvDbSharper (https://github.com/HristoKolev/TvDbSharper) and i have a question about IEnumerable.
What i'm trying to do is get all the Id for a given series and then add the result in a listView.

This code gives me the first Id in the list:

const int SeriesId = 78804;

var tasks = new List<Task<TvDbResponse<BasicEpisode>>>();

var firstResponse = await client.Series.GetEpisodesAsync(SeriesId, 1);

for (int i = 2; i <= firstResponse.Links.Last; i++)

{

tasks.Add(client.Series.GetEpisodesAsync(SeriesId, i));

}

var results = await Task.WhenAll(tasks);

var episodes = firstResponse.Data.Concat(results.SelectMany(x => x.Data));



epsListview.View = View.Details;

epsListview.Columns.Add("Episode", 100);

string arr = new string[4];

ListViewItem itm;

arr[0] = episodes.First().Id.ToString();

itm = new ListViewItem(arr);

epsListview.Items.Add(itm);

but what i want is to make a new line in the epsListview for each id available.

I never used IEnumerable and i'm still very novice using c#, i've been stuck with this problem for over a week now. can anyone help me with this ?

Thanks!!

Maybe I'm misunderstanding the question, but .ToList() will convert an IEnumerable into a List.

Do you know how to use a foreach statement?

It looks like you're wanting to build an array of IDs from an IEnumerable of episodes, and add that array to a single ListViewItem. This should do that.

string arr = episodes.Select(episode => episode.Id.ToString()).ToArray()

ListViewItem itm = new ListViewItem(arr);

epsListview.Items.Add(itm);
