Cannot resolve the return value from a client object WebService

I don't understand how to fix this issue. I will need your help and explanation on how to fix it. I used a WebService to populate a DropDownList with artist names.
Here is the code behing.

private List<ArtistServiceReference.ArtistServiceClient> ArtistDetail()
{
    ArtistServiceReference.ArtistServiceClient client =  
      new ArtistServiceReference.ArtistServiceClient();

    ArtistServiceReference.Artist[] artists = client.ArtistDetail();

    return artists.ToList();   <=== errror here

Cannot implicitly convert type System.Collections.Generic.List<ArtistServiceReference.Artist> to System.Collections.Generic.List<ArtistServiceReference.ArtistServiceClient>

Here is the ArtistService.cs

public class ArtistService : IArtistService
{
    public List<Artist>  ArtistDetail()   
    {
        using (ArtistDataContext db = new ArtistDataContext())
        {
            return (from artist in db.Artists

                select new Artist()
                {
                    Id = artist.Id,
                    Artist_nom = artist.Artist_nom
                }).ToList();
        }
    }
}

here is the solution:

code behind.cs

private List<ArtistServiceReference.Artist> ArtistDetail()
{
    ArtistServiceReference.ArtistServiceClient client = new 
    ArtistServiceReference.ArtistServiceClient();

    ArtistServiceReference.Voiture[] artists = client.ArtistDetail();

    return artists.ToList();
}

ArtistService.cs

public class ArtistService : IArtistService
{
    public List<Artist>  ArtistDetail()  
    {
        using (ArtistDataContext db = new ArtistDataContext())
        {
            return db.Artists.ToList();
        }
    }
}

Your return type on your method should be a list of ArtistServiceReference.Artist as opposed to a list of ArtistServiceReference.ArtistServiceClient. You want to return a list of Artists by using the ArtistServiceClient, you are not returning a list of the clients.

private List<ArtistServiceReference.Artist> ArtistDetail()
{
    ArtistServiceReference.ArtistServiceClient client =  
      new ArtistServiceReference.ArtistServiceClient();

    var artists = client.ArtistDetail();

    return artists.ToList();
}

If you want your client method to return a list of Artists, why do you declare it as returning a list of ArtistClients?

The following should fix your issue:

private List<ArtistServiceReference.Artist> ArtistDetail()
{
    ...
    return artists.ToList();
}

or, even more elegant:

using YourNamespace.ArtistServiceReference;

private List<Artist> ArtistDetail()
{
    ...
    return artists.ToList();
}
