C# Need help to memory game

Question

this snippet below is my code.

It's supposed to be a memory game, but i have some problems making it work, I've made a button_1 that generates 6 random numbers in random order, those 6 numbers are supposed to tell the "p1 - p6" (pictures (2 of each to make pairs)) what picture boxes, they're getting in to, I'd really like it to be random what pictures, goes into the picture boxes.
problems i have:

1. random numbers cant get into the array "R[6]" and then i cant use it down in the "pictureboxes" to get assigned to a picture.
2. when 2 pictures are flipped with the same picture, i need them to disappear, (after a timer)

its supposed to give point for every pair of match,
in this code, there's only 6 picture boxes, i need like 25-30
i only got 3 different pictures in this code, again i need like 6 so that there's 5 pairs of each picture if you got any solutions, or questions regarding what i need in my game, please e-mail me on <<snip>>

A much cleaner way would be to initialise your images and associate the Tag property with their name:

Image imgOne = Resource.YourImage;
imgOne.Tag = ImageNameString;

Then initialise your Image List:

List<Image> imageList = new List<Image>{// Your Images};

Then initialise your PictureBox list:

List<PictureBox> pictureBoxList = new List<PictureBox>();

Ok now we have the basics set up. Begin assigning randomly. Once one picture has been assigned to the picture box, remove it from the list:

while(imageList.Count > 0)
{
     int imageIndex = //random number between 0 and (imageList.Count - 1);
     PictureBox tempBox = new PictureBox { Image = imageList[imageIndex], OnClick = PictureBox_Click };
     picturBoxList.Add(tempBox);
     imageList.RemoveAt(imageIndex);
}

Ok, now remember how the Tag was set before? This stores any information you want. It takes the Object type so you can box and un-box. In this case we've saved a string (your image name).

In order to make a comparison, include a Private PictureBox variable to your form. Here you will save your first selection.

When you make your second selection, compare the tags (you can convert them to strings first, I have assumed you'll be doing this in a Form Wide PictureBox_Click event):

private void PictureBox_Click(object sender, EventArgs args)
{
     // Psuedo code, I don't want to give it allll away ;)
     // Check if first selection variable is null
     // If true, cast sender to PictureBox, store in first selection variable and return
     // else, perform the code below
     String firstString = (String)firstSelection.Image.Tag;
     String secondString = (String)((PictureBox)sender).Image.Tag;
     if(firstString.Equals(secondString))
     {
          // Do your fade out stuff
     }
     firstSelection = null;
}

And that's it pretty much done.

As you can see it's a lot clearer and concise than the old way :)

At a code level, implementing it this way is VERY scalable, but there is nothing to put the picture boxes onto the form. I'll leave that for yourself :)

// firstly, let's make it easier to use these:
    /*

    Image p3 = Properties.Resources.Toco_Toucan;
    Image p4 = Properties.Resources.Toco_Toucan;
    Image p5 = Properties.Resources.Green_Sea_Turtle;
    Image p6 = Properties.Resources.Green_Sea_Turtle;
    */
    Image[] images = new Image[6] // I have made an array and initialized it, it will be easier to use later
    {
