In this post, we will see how can we fill the Asp Menu by specifying folder instead of some other data source. Following is the folder structure which this code is supportedRoot-> Folder 1 -> Files-> Folder 2 -> Files-> Folder 3 -> FilesI mean, if there is another folder in Folder 1 or Folder 2 or Folder 3. The code will not detect because it is not recursive.So Let's get down to the code

protected void Page_Load(object sender, EventArgs e){DirectoryInfo di = new DirectoryInfo(@"C:\\agha"); //Path of folder you want get file/folder fromDirectoryInfo[] objDi = di.GetDirectories();foreach (DirectoryInfo d in objDi){MenuItem objMenuItem = new MenuItem(d.Name);FileInfo[] objfi = d.GetFiles("*.*");foreach (FileInfo f in objfi){objMenuItem.ChildItems.Add(new MenuItem(f.Name));}Menu1.Items.Add(objMenuItem);}}
