title: C#: how to check and display the content of a folder?
body: <p>I'm not sure whether this topics has been disscussed before or not, but I'm not sure the exact word to search for it. What method/class should I use?</p>
  
  <p>The program has 3 buttons: <strong>1) for folder browsing, 2) scan for the selected folder content, and  3) open the file.</strong> When user browse the selected folder**(1)<strong>, user click scan button to scan from the first file until the last available files and listed it text box</strong>(2)** and from that user can decide whether to open the files or not**(3)**.</p>
  
  <p>Here are what have I done so far (no 1 and 3):</p>
  
  <pre><code>//For browse.
  private void browse2()
  {
      if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
       {
          this.txtDest.Text = folderBrowserDialog1.SelectedPath;
       }
  }
  
  //For opening folder.
  private void btnOpen_Click(object sender, EventArgs e)
  {
      try
      {
          Process.Start(txtDest.Text);
      }
      catch
      {
          MessageBox.Show("Please select one file/folder");
      }
  }
  </code></pre>
