Hi, noob question

Thank you in advance,
My problem with the code is that i want to swap p1 which is a picturebox for a different picture box as it loops. I have 100 pictureboxes that i need to loop throughm but i can't figure out how to swap p1 for p2 and so on..

Code:

---


  public Form1()
        {
            InitializeComponent();

            int row = 0, column = 0; // used for 2d array

            for (int count = 1; count < 101; count++)
            {
                boxes[row, column] = p1;

                if (column == 10)
                {
                    row++;
                    column = 0;
                }
            }
           
        }
        PictureBox[,] boxes = new PictureBox[10,10];

Do use code tags to post your code and keep it's formatting.
e.g [code] your code goes here [/code]

My First suggestion is that you put your implementation in a method.

If you intend randomly swapping your pictures then use a random number generator in your implementation.

Will BRB to explain better.

Sorry I've been away for a while and couldn't respond to your post early enough.

Here's what I've to say. If you want to loop through a multidimensional array of the rectangular type, that is an array where each row has the same number of columns.

e.g:

Code:

---

PictureBox[,] myPictireBoxes = new PictureBox[10,10];

---

You'll have to loop through each row and column respectively. To do this use the Array.GetLength(int dimension) method in your for statement. Where parameter dimension is zero based, 0 for row and 1 for your column.

See an example below.

Code:

---

            // creating a picture box array
            PictureBox[,] myPictureBoxes = new PictureBox[2,2];

            // initializing myPictureBoxes
            for (int rowCounter = 0; rowCounter < myPictureBoxes.GetLength(0); rowCounter++)
            {
                for (int columCounter = 0; columCounter < myPictureBoxes.GetLength(1); columCounter++)
                {
                    myPictureBoxes[rowCounter, columCounter] = new PictureBox();
                }
            }

---

If I'm to randomly assign pictures to this boxes. I'd do this:

Code:

---

            // add images randomly to these boxes
            foreach (var pictureBox in myPictureBoxes)
            {
                pictureBox.Image = GetRandomImage();
            }
       

        /// <summary>
        /// Randomly get images from the resource manger
        /// </summary>
        /// <returns>A random image.</returns>
        private Image GetRandomImage()
        {
            string randomImage = string.Format("picture{0}", randonNumber.Next(4));
            Image newImage = (Image)Properties.Resources.ResourceManager.GetObject(randomImage);
            return newImage;
        }

---

Where the pictures in my resource manager are named picture1, picture2, picture3 and picture4 respectively.
Please note that all other code blocks except the GetRandomImage() code block should be in a method.
