Sort files on Date modified or created in asp.net using C# -


i need sort files based on date , time last created or modified , show latest added file in first. asp.net form uploading files on webserver , after uploading, default files organised on basis of name or should in alphabetic order. so, can 1 me sort , organise on basis of time uploaded.

protected void getfiles() {     system.text.stringbuilder sbld = new system.text.stringbuilder();     if (directory.exists(server.mappath("~/package_image/")))     {         directoryinfo dirmail = new directoryinfo(server.mappath("~/package_image/"));         fileinfo[] defaultfiles = dirmail.getfiles();         foreach (fileinfo filedir in defaultfiles)         {             if (filedir.extension.tolower() == ".jpg" || filedir.extension.tolower() == ".gif" || filedir.extension.tolower() == ".png" || filedir.extension.tolower() == ".jpeg" || filedir.extension.tolower() == ".bmp")             {                 // need sorting on basis of date-time, created or uploaded.                 sbld.append("<div class='itembox'><table width='100%'><tr><td height='160'><img width='200' src='../package_image/" + filedir.name + "'></img></td></tr></table></div>");             }         }         literal1.text = (sbld.tostring());     } }

the sorting might using c#, done server itself, or if possible can javascript or jquery, can processed @ client itself.

quite simple. make sure have reference system.linq added next other using statements. 

//using system.linq protected void getfiles() {     system.text.stringbuilder sbld = new system.text.stringbuilder();     if (directory.exists(server.mappath("~/package_image/")))     {         directoryinfo dirmail = new directoryinfo(server.mappath("~/package_image/"));         fileinfo[] orig = dirmail.getfiles();                 // sort on server         fileinfo[] defaultfiles = (from file in orig orderby file.creationtime select file).toarray();         foreach (fileinfo filedir in defaultfiles)         {             if (filedir.extension.tolower() == ".jpg" || filedir.extension.tolower() == ".gif" || filedir.extension.tolower() == ".png" || filedir.extension.tolower() == ".jpeg" || filedir.extension.tolower() == ".bmp")             {                 // need sorting on basis of date-time, created or uploaded.                 sbld.append("<div class='itembox'><table width='100%'><tr><td height='160'><img width='200' src='../package_image/" + filedir.name + "'></img></td></tr></table></div>");             }         }         literal1.text = (sbld.tostring());     } }
