TreeNode node = new TreeNode();
node.Name = openFileDialog1.FileName;
node.Text = openFileDialog1.FileName;
node.ImageKey = GetImageKey(openFileDialog1.FileName);
node.SelectedImageKey = GetImageKey(openFileDialog1.FileName);
treeView1.Nodes[0].Nodes.Add(node);
Application.DoEvents();
treeView1.Refresh();
}
}

private string GetImageKey(string imagepath)
{
string imagekey = imagepath;

if (!imageList1.Images.ContainsKey(imagekey))

Image img = Image.FromFile(imagepath);

imageList1.Images.Add(imagekey,img);
Application.DoEvents();
}
return imagekey;
}
