open file dialog return multiple file names (Visual Basic 2010 C#)

Question

How to make a OpenFileDialog1 object return multiple paths of the selected files to a multi-line textbox?

Answer 1

I've created some code for you to use:

private void SomeMethod()
{
    string[] lines = GetFileNames();

    if (lines != null)
        textBox1.Lines = lines;
}

private string[] GetFileNames()
{
    var dialog = new OpenFileDialog()
    {
        Multiselect = true
    };

    if (dialog.ShowDialog() == DialogResult.OK)
        return dialog.FileNames;
    else
        return null;
}

I hope it helps.
