copied!<p>You could keep track of the images in another array.</p> <p>After you add the image to the view you should also add it to the array:</p> <pre><code>images[j] = mole; </code></pre> <p>Then later:</p> <pre><code>if (CounterArray[j] == 0) { grid_Main.Children.Remove(images[j]); } </code></pre> <p>But using static arrays and separating data is not a good idea.</p> <p>If you can you should better aggregate all the metadata and the image together in the same structure:</p> <pre><code>class Mole { public int Counter { get; set; } public Control Image { get; set; } } </code></pre> <p>and manage them in a single <em>List<Mole></em>; adding and removing them will be simpler.</p> <p>Here is some code that illustrates the idea (won't compile):</p> <pre><code>class Mole { public int X { get; set; } public int Y { get; set; } public int Counter { get; set; } public Control Image { get; set; } public bool IsNew { get; set; } } class Test { IList<Mole> moles = new List<Mole>(); private static void AddSomeMoles() { moles.Add(new Mole{ X = rand.Next(100), Y = rand.Next(100), Counter = 3, Image = new PictureBox(), IsNew = true }); } private static void DisplayMoles() { foreach (Mole mole in moles) { if (mole.IsNew) { grid_Main.Children.Add(mole.Image); mole.IsNew = false; } } } private static void CleanupMoles() { foreach (Mole mole in moles) { mole.Counter -= 1; if (mole.Counter <= 0) { grid_Main.Children.Remove(mole.Image); moles.Remove(mole); } } } static void Main() { while (true) { AddSomeMoles(); DisplayMoles(); Thread.Sleep(1000); CleanupMoles(); } } } </code></pre>
