Question

I use OpenFileDialog class, to open and display a filename chosen.

      List<string> paths;
    private void openFileDialog1_FileOk(object sender, CancelEventArgs e)
    {
         label1.Text = "Now you can save the file paths or remove them from the list above";
         paths.Add(openFileDialog1.FileName);
         listBox1.DataSource=paths ;//Only one file is displayed in the listbox
         Refresh();

    }

I want the user to choose several files and display all the files that he chose in the listbox that i have. The problem is that only one file path is displayed each time. What is funny, is that i thoguht that whenever i use pahts.Add,,new filename is added, but in reality it isnt so!?!

You have to set Multiselect in your file dialog to true and then use the FileNames property:

private void openFileDialog1_FileOk(object sender, CancelEventArgs e)
{
   string[] files = openFileDialog1.FileNames;
   paths.AddRange(files);
   listBox1.DataSource=paths;
   Refresh();
}
