How to access FIle names from any folder at runtime ???

09-29-2008 3:41 AM |

Hello All,

I want to access names of the files from the any folder in windows. I have used C# with silverlight and  I tried to do following steps

page.xaml

<UserControl
    xmlns="http://schemas.microsoft.com/client/2007"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="YetAnotherCarousel.Page"
   
    >
    <!--Width="1024" Height="768"-->

    <Canvas x:Name="LayoutRoot" Background="Black" Width="1200" Height="800" >
    </Canvas>
</UserControl>

page.xaml.cs

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.IO;

namespace YetAnotherCarousel
{
    public partial class Page : UserControl
    {
        public Page()
        {
            // Required to initialize variables
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(Page_Loaded);
        }

private void CreateImage()
        {
            Carousel carousel = new Carousel();
            Image[] imgObj = new Image[100];
            int j = 1;

          string[] fileEntries = Directory.GetFiles("D:/YetAnotherCarousel/YetAnotherCarousel/imges");   ERROR COMES HERE

           foreach (string fileName in fileEntries)
              {

                        Image imge = new Image();
                        imgObj[j] = imge;
                        imgObj[j].Source = new BitmapImage(new Uri(fileName, UriKind.Relative));
                        imgObj[j].Stretch = Stretch.Fill;
                        imgObj[j].Width = 400;
                        imgObj[j].Height = 300;
                        carousel.CreateItem(imgObj[j],fileName);    //  CreateItem is a separate function in Carousel.cs
                        j = j + 1;

                 } 

               this.LayoutRoot.Children.Add(carousel);

              }

               void Page_Loaded(object sender, RoutedEventArgs e)
              {

                          CreateImage();

              } 

}

 Problem

So when I rebuild the solution it rebuilds successfully . But, when I run the program in browser it shows the error :::

( error locator symbol) / 4th row of createImage function

    "MethodAccessException was unhandled by  User Code"

    "Attempt to access the method failed: System.IO.Directory.GetFiles(System.String)"

I have full access rights to my system. But, still I am unable to solve the problem.

Please help me. It really mkaing me mad. As I tried doing the same thing in normal c# and its running perfectly there but not running here in silverlight

 Disclaimer:

PLEASE EXCUSE ME , if I asked some very basic thing , as I am new to Silverlight and trying my best to get the hands on this technology.
