C＃如何从IEnumerable中列出

Question

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!!

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);
