C # traverse the file folder directory under all the pictures and the file code sharing under the Traverse folders

In the last project development encountered such a requirement, take all the pictures under the specified directory, the form of the table to show and display the relative path of the picture. The following small series to share the C # traverse the folder directory of all the pictures and the files in the traversal folders, together to see it

Requirements: Take all the pictures under the specified directory, display the table's style and display the relative path of the picture.

Service-Side code:

Public partial class ViewIcon:System.Web.UI.Page {  jarray ja = new Jarray ();//define an array public  string info = Strin G.empty;   protected void Page_Load (object sender, EventArgs e)  {   var path1 = system.appdomain.currentdomain.basedirectory;//Gets the assembly directory   String path = Path.Combine (path1, "Image", "menu");// Path.Combine combines 3 strings into a path   of var images = Directory.GetFiles (path, ".", Searchoption.alldirectories). Where (s = S.endswith (". png") | | s.endswith (". jpg") | | s.endswith (". gif"));   Images = Directory.GetFiles (path, "*.png|*.jpg", searchoption.alldirectories);   Directory.GetFiles returns the file path of the specified directory searchoption.alldirectories specifies the search current directory and subdirectories   //Traversal string type images array   foreach ( var i in images) {    var str = i.replace (path1, "");//Get relative path    var path2 = str. Replace ("\ \", "/"); convert the character "\ \" to "/"    ja. ADD (path2);   }   info = Newtonsoft.Json.JsonConvert.SerializeObject (JA);//serialized to String  }}

Front-End Code:

<script type= "Text/javascript" > $ (function () {var images = <%=info%>;  var list = [];  List.push ("<table>");   List.push ("<thead>");   List.push ("<tr>");   List.push ("<td> icon </td>");   List.push ("<td> path </td>");   List.push ("<td> icon </td>");  List.push ("<td> path </td>");   List.push ("</tr>");  List.push ("</thead>");  List.push ("<tbody>"); $.each (images, function (A, b) {if ((a+1)%2==0) {List.push ("<td>" + "</td> ");    List.push ("<td>" +b+ "</td>");    List.push ("</tr>");     } if ((a+1)%2!=0) {List.push ("<tr>"); List.push ("<td>" + "</td> ");   List.push ("<td>" +b+ "</td>");  }}) List.push ("</tbody>");  List.push ("</table>");  List.push ("<br>");  var images = List.join (""); $ ("#imgs"). Append (imagES); }) </script>

As follows:

below to introduce you to the C # Traverse folder under all subfolders of the file, get the file name

Suppose the A folder is under the F disk, the code is as follows. Export the file name to a ListBox

Using system.data;using system.drawing;using system.linq;using system.text;using system.windows.forms;using System.io;namespace windowsformsapplication1{public  partial class Form1:form  {public    Form1 ()    {      InitializeComponent ();    }    private void Button2_Click (object sender, EventArgs e)    {      DirectoryInfo thefolder = new DirectoryInfo (@ "F:\a\") ;      directoryinfo[] Dirinfo = Thefolder.getdirectories ();      Traverse Folder      foreach (DirectoryInfo nextfolder in Dirinfo)      {         //THIS.LISTBOX1.ITEMS.ADD (nextfolder.name);        fileinfo[] FileInfo = Nextfolder.getfiles ();            foreach (FileInfo nextfile in FileInfo)//Traverse file        this.listBox2.Items.Add (nextfile.name);}}}
