c# - 将 foreach 语句重写为 linq

Question

我仍在学习 LINQ，请耐心等待 :)。我的问题，如何将以下代码转换为 LINQ

int count = 0;

foreach (var item in settings.FavouritesSetting)
{
   if (item.FavouriteType != Constants.FavouriteType.Folder)
      count++;
}

return count.ToString();

Answer 1

var count = settings.FavouritesSetting.Count(i => i.FavouriteType != Constants.FavouriteType.Folder);

return count.ToString();
