Accepted answer
You already have Files string[] as global variable defined in Form 1, you can use this in Form 2 like below code
public static string[] Files;   // global variable in Form1
private void btnopenfiles_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
files = ofd.SafeFileNames;
paths = ofd.FileNames;
for(int i =0;i
{
listBox1.Items.Add(files[i]);
}
}
}

// form 2

private void Form2_Load(object sender, EventArgs e)
{
label1.Text = Form1.Files[0];   // here you can loop through Files
}

           comboBox1.DataSource = list;
           comboBox1.Name = "MediaList";
       }


       private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)

       }
