Erreur : does not contain a definition

Bonjour,

J'essaie de compiler le code ci-dessous mais j'obtiens une erreur.
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 using System; public class Song { private string name; public Song nextSong { get; set; } public Song(string name) { this.name = name; } public void setNextSong(Song nextSong) { this.nextSong = this.nextSong; } public bool isRepeatingPlaylist() { Song slowStep = this; Song fastStep = this; while (((fastStep != null) && (fastStep.nextSong != null))) { slowStep = slowStep.nextSong; fastStep = fastStep.nextSong.nextSong; if ((slowStep == fastStep)) { return true; } } return false; } public static void Main(string[] args) { Song first = new Song("Hello"); Song second = new Song("Eye of the tiger"); first.nextSong = second; second.nextSong = first; Console.WriteLine(first.IsRepeatingPlaylist()); } }
L'erreur est la suivante :

Merci pour votre aide

Bonjour,

Il aurait été intéressant de voir le code de PlaylistTest aussi mais dans ton cas pas besoin de l'avoir, les erreurs sont très parlantes :

Tu appelles des variables et des méthodes avec une majuscule alors que tu les a définies sans majuscules :

Petit rappel: En C#, on mets toujours une majuscule au début d'un nom de méthode, et c'est valable aussi pour les variables qui sont publiques.

Merci beaucoup. ça compile.

Ça ne sert strictement à rien.

Effectivement je me suis trompé.

Merci pour votre remarque.
