Dynamically add Picture box using C# delegate

The below code is just abstract just to show simple use of delegate
using System.Data;
using System.IO;
using System.Drawing; using System.Text; using System.Threading; public partial class ImageView : Form{
Mydel a;
public delegate void Mydel(PictureBox p); public ImageView(){ InitializeComponent(); }
private void ImageView_Load(object sender, EventArgs e){
a = new Mydel(Add); Thread t = new Thread(load); t.Start(); }
public void load(){
DirectoryInfo dinfo = new DirectoryInfo(@"F:\Mypics"); FileInfo[] finfo = dinfo.GetFiles(); Graphics g = panel1.CreateGraphics(); int x = 20; int y = 20; for (int i = 0; i if (Image.FromFile(finfo[i].FullName) != null){
PictureBox p = new PictureBox(); p.Image = Image.FromFile(finfo[i].FullName);
p.SizeMode = PictureBoxSizeMode.StretchImage;
p.Left = x; p.Top = y;
p.ImageLocation = finfo[i].FullName;
p.Width = 140; p.Height = 90;
Object[] obj = new Object[1];
obj[0] = p;
Controls[Controls.IndexOf(panel1)].Invoke(a, obj); x += 150;
if (x > this.Width-100){
y += 100; x = 20; }
} if (i > 35) break;
}
}
public void Add(PictureBox p) {
panel1.Controls.Add(p);
}
}
}
