ArrayList 元素

//目錄條目類public class FolderItem{    public string filename;    public string filetype;    public int size;    public int number;    public FolderItem(string filename, string filetype, int size, int number)    {        this.filename = filename;        this.filetype = filetype;        this.size = size;        this.number = number;    }    }

排序方法類

//目錄上傳時間排序public class FolderItemCompare : IComparer{    public int Compare(object manA, object manB)    {        FolderItem man1 = (FolderItem)manA;        FolderItem man2 = (FolderItem)manB;        return man1.number.CompareTo(man2.number);    }}

調用：

ArrayList arrList = new ArrayList();arrList.Add(item);//...arrList.Sort(new FolderItemCompare());
