using folder browser dialogue,need to add image

Question

Hello friends,

I have tried to add more number of images with path into Listview using FolderBrowserDialog,I used below code, But I'm getting error. Can any one tell how to resolve this problem.

private void btnBrows_Click(object sender, EventArgs e)
{
FolderBrowserDialog browsefolder = new FolderBrowserDialog();
if (browsefolder.ShowDialog() == DialogResult.OK)
{
listviewbin.Items.Clear();

string[] myfiles = Directory.GetFiles(browsefolder.SelectedPath);
foreach (string file in myfiles)
{
int i = 0;
ListViewItem myitem = new ListViewItem(file, i);
imageList1 = new ImageList();
imageList1.Images.Add(Image.FromFile(file));
i++;
if (i == imageList1.Images.Count - 1)
{
i = 0;
}

listviewbin.Items.Add(myitem);
}

}
