Asp.net 如何将不同的播放列表标题从数据库绑定到复选框列表

它不会将不同的值带到复选框列表中。请帮我解决这个问题

也许正是由于这个原因（

Distinct

compare the reference…）？您是否尝试了上述主题中的一个答案，现在是否有效？@SamuelCaillerie抱歉回复太晚。问题已经解决

private void chkDeletePlaylistBind()      
{     
   chkDeletePlaylist.DataSource = objEntities.Playlists.OrderBy(del => del.PlaylistTitle).Distinct();
   chkDeletePlaylist.DataTextField = "PlaylistTitle";
   chkDeletePlaylist.DataValueField = "PlaylistID";
   chkDeletePlaylist.DataBind();
}
