Problems inserting image from directory

I am having some problems inserting a image i have in my directory. I search through the resources I have on the internet and manage the relevant code to be use.

pictureArray[] > is a field

Created using this code:

using System;  
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    class Field
    {

        public PictureBox picbox; 

        public Field()
        {
            picbox = null;
        }

    }
}

At the top of the code, i initalize it:

private Field[] pictureArray = new Field[100];

The portion of my code as following:

pictureArray[0].picbox = new PictureBox();
pictureArray[0].picbox.Image = System.Drawing.Image.FromFile(@"..\Postlogger\test.jpg");
pictureArray[0].picbox.Location = new System.Drawing.Point(17, 19);
pictureArray[0].picbox.Name = "picBox";
pictureArray[0].picbox.Size = new System.Drawing.Size(50, 50);
this.groupBox1.Controls.Add(pictureArray[0].picbox);

My image doesn't appear on my screen. Any suggestion to what i have done wrongly? Thanks!

I can see problem in your code :)

You have declared array of reference type

private Field[] pictureArray = new Field[100];

If you try and debug you will see all elements in pictureArray are null. On the next line you are doing

pictureArray[0].picbox = new PictureBox();

I believe it is throwing exception here as pictureArray[0] is null. Please instantiate Field object before referring it.

pictureArray[0] = new Field();

pictureArray[0].picbox = new PictureBox();

This should work now.
