why don't you set the Image property before adding picturebox1 to controls?

Where are you declaring your picturebox1? I think the object is not int the scope of your class. try to create as public and do.

You have to make for your form a member first:
private PictureBox picturebox1;

In the form constructor you can set the properties of the picturebox1 object. After this in the button click event you can use your PictureBox object without problem.

By the way you can iterate through the controls with foreach. Maybe you can find your dynamically created control as the follows:
foreach (var i in this.Controls)
    if (i.GetType() == typeof(PictureBox))
        Image p = i as Image;

        p.Image = //your code

I hope I could help you!

namespace WindowsFormsApplication6
partial class Form1
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
if (disposing && (components != null))
#region Windows Form Designer generated code

private void InitializeComponent()
this.buttoncreatepicturebox = new System.Windows.Forms.Button();
this.buttonshowimage = new System.Windows.Forms.Button();

// buttoncreatepicturebox

// buttonshowimage

// Form1

private System.Windows.Forms.Button buttoncreatepicturebox;
private System.Windows.Forms.Button buttonshowimage;
private System.Windows.Forms.PictureBox picturebox1; // i wrote this manually
//We have to make for our form a member first

private void button1_Click(object sender, EventArgs e)
picturebox1 = new PictureBox();


picturebox1.Name = "picturebox1";
picturebox1.Location = new Point(0, 0);
picturebox1.Size = new Size(100, 100);
