SortFileList.aspx.cs

using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.IO; public partial class SortFileList : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { DirectoryInfo dirinfo = new DirectoryInfo(MapPath("~")); FileInfo[] sortList = dirinfo.GetFiles(); Array.Sort(sortList, new MyDateSorter()); foreach (FileInfo item in sortList) { Response.Write(item.FullName + "<br" + " />"); } } } public class MyDateSorter : IComparer { #region IComparer Members public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = (FileInfo)x; FileInfo yInfo = (FileInfo)y; //依名稱排序 return xInfo.FullName.CompareTo(yInfo.FullName);//遞增 //return yInfo.FullName.CompareTo(xInfo.FullName);//遞減 //依修改日期排序 //return xInfo.LastWriteTime.CompareTo(yInfo.LastWriteTime);//遞增 //return yInfo.LastWriteTime.CompareTo(xInfo.LastWriteTime);//遞減 } #endregion }

執行結果:(依名稱遞增排序)
