i am working on windows form application and i want to play a video file in media player from list box.i get those video files from my project directory and kept in list box.the source code shows an error when i pass the URL to ax-media player that is "can not implicitly convert type object to string".how can i fix this or is there any other way to play that video.

here is the code

private void button1_Click(object sender, EventArgs e)

{

string path = @"abc";

foreach (string s in Directory.GetFiles(path, "*.mpeg4").Select(Path.GetFileName))

listBox1.Items.Add(s);

}

private void button2_Click(object sender, EventArgs e)

{

listBox1.SelectedItems.Clear();

for (int i = 0; i < listBox1.Items.Count; i++)

{

if (listBox1.Items[i].ToString().Contains(cmbox_tchr.SelectedItem.ToString()))

{

listBox1.SetSelected(i, true);

}

}

}

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
