如何在列表框中顯示列表

Question

試圖在列表框中打印歌曲刺激。我試着將它們添加爲項目，但只是打印windowsform1.cs。我是否必須轉換項目，或者他們是我需要爲列表框打印字符串和int的函數。

private string title; 
private string album, title, artist, genre; 
private int length; 

private void List_Click(object sender, EventArgs e) 
{ 
    MDB.listAllSongs(listBox1.Items); 

} 

public void listAllSongs(IList list) 
{ 
    List<Song> allSongs = new List<Song>(); 
    foreach (Album album in albums) 
    { 
     album.listSongs(allSongs); 
    } 

    foreach (Song song in allSongs) 
    { 
     list.Add(song.ToString()); 
    } 
} 

public void listSongs(List<Song> list) 
{ 
    foreach (Song song in songs) 
    { 
     list.Add(song); 
    } 
} 

Answer 1

您需要實現toString（）方法中的宋級，來回報您的歌曲的標題：

public string toString() 
{ 
    return title; 
}
